today I experienced an unexpected transaction from one of my wallets, all my assets were sold automatically, this is the first time I've experienced this, I didn't protect this wallet with a PIN and 2fa
can it be delayed after I use 2fa and PIN for all transactions?

The question is what app that you have been used to store your money? If your 2 FA didn't work and i do believe if there would be something wrong with you or your app and if you didn't mention what kind of wallet or app that already used. You can try to enable 2FA verification and any withdrawal that will be  happening in your wallet will require 2fa to be able to take it from your wallet. This is adding second security layer to your wallet but it's better if you can encrypt it as well. This is increasing the security of your wallet. Im always using 2 fa for every wallet or assets to make it even safer.

For transactions that have already occurred, it is not possible to delay or cancel transactions after applying 2 FA and PIN authentication.

However, if you apply 2 FA and PIN previously, events such as automatic asset sales or hacking activities on your wallet will not occur. At least your funds will be safe from hacking activities or cases like you experienced. PIN and 2 FA authentication are additional security which I think is good and effective for protecting crypto assets in the wallet, I suggest using these 2 additional security in other wallets you have.

Please correct me if my statement is wrong

That's why people should enable 2FA authentication for the security of a wallet or should be used in everything  important . However, in many cases hackers can also break the 2FA security system. In many cases there are many exchangers who have weak 2FA security system , in that case the users get a lot of problems with it .

If the transaction is already running and only waiting for confirmation from the network, then it will never be delayed and also will not mean anything even though you have implemented 2fa and the PIN in the wallet, but if the transaction has not been executed by the network, then it is also possible to fail. Hopefully there are no other transactions that happen suddenly to your wallet.

Nothing is 100% safe but 2FA is considered "safe". Also there are different 2FA's. SMS, Google, hardware, mobile app... All of those have different weaknesses. SMS 2FA is considered the weakest of all but I don't know the exact reason. It is probably because hacking simcards is somehow easier.

You should use 2FA on every important or not account you have. Banks, emails, forums (if there is an option), social media. If a hacker can get into one of those accounts, he can start collecting your data and he will strike you when he finds a weakness.

What do you mean automatically sold? Do you mean this is an exchange wallet?
If they were already sold then, the transaction is already done. Either someone already got control of that account and if you have not set the email, Authentication and 2fa, maybe they can withdraw the funds too.  I could only think someone has access to you email and learned about your account and its worse if they have also done SIM swap.

Sure it will be if you only have used it. It wouldn't have taken so easily if there's some kind of security to protect your asset in the first place, a 2fa with the app, SMS, or email should delayed the exploiter. There's a huge chance that it wouldn't be sold if there's some security like 2FA on your app or wallet to be specific.

I think 2fa is safe for wallet.if you use a 2fa don't be transection any one your wallet.Many hackers find out opportunities to unsecure a wallet.without 2 fa wallet is unsecur because in many hackers try also break the 2fa security system.They are can't to easy to break the 2fa security system.If you add a 2fa hackers don't do this.Nothing is impossible for hackers,but it is better to be secure.I am using already 5 years 2fa and pin.I think this 2fa protect my wallet and i believes this.  

by activationg 2fa or pin for each transaction we have multple layer security for accessing account , trading or about finance operation. no one could sell our asset if we activate 2fa , it is as confirmation for all account operation. google auth or sms    be best 2fa in my opinion because only us that hold this device.

Sometimes they say it is better late than being absent and there are many saying like that too, so you have to know it that if you had activated such security then you won't have such encounter. I don't know if this is hacking of your wallet that has caused a transaction that you didn't activate. And I believe you should get email before such is done your approval is required if you didn't activate 2FA .

2FA always enable it whenever there is money involved. The most android application now are covered by Google Protect but it doesn't mean you are safe so better if you have one more wall for security.
Now if you are running a desktop software you could just do the same case. If not password which should not be written/saved on the same computer where the software is, better save it old school by writing it in a paper or 2FA too which is a feature now for most wallets.
I am sorry, but your funds might be long gone.
You could try tracing it.
1. If it was sent to an exchange and you can identify what exchange it is then you can warn them about the funds being hacked by showing proof. There's a chance they will freeze it. But that's a lot of work. Is it worth the hacked amount to make that kind of effort?
2. If it's sent to a wallet address with an "idiot" hacker that was signed by him then you trace him. But that's unlikely to happen.

If you use your 2fa for any types of phissy website then it will obviously not working for your money safety because web developer also see your 2fa code here and he also can add 2fa on any types of 2fa app but insted of that if you use it for any types of real website then its fine for you.

The importance of 2fa for keeping your account or your wallet safe is immense.If your account is automated by 2FA, hackers will never be able to hack your account.I think for those who work in cryptocurrency, you must use 2FA to save the account. This will keep your account 100% secure.

our regret will always come lately , and unfortunately why we don't doing this since early to prevent unexpected accident. for every worthed account we must secure it with multiple layer authentification , we could using sms code or google auth. with this additional setting i am believe someone will hard to access our account.

All of these precautions are good when a code is requested for a withdrawal. And if your wallet is hacked, that is, your keys are compromised, then it's too late to do anything. You should always set protection initially, even if there are no assets. Because in the future they may appear there and you have everything already protected.

What wallet do you use because only exchange wallets apply 2fa and PIN for all transactions because if sold and automatic withdrawals you have to check the email registered with the exchange. I think if you own assets then you have to enable security to keep assets hackable.

You should have put a PIN or password for transaction on your wallet even when you are not comfortable using 2fa. That would have saved your assets. This steps are necessary in safeguarding our wallets but alot of us think it is a stress doing all that checks. Nothing is as stressful as what happens when your wallet is hacked and you try to recover it. I hope the hack is not an insider job or you downloaded a virus on your device for the hacker to have gotten access to your wallet.

Can you specify what type of wallet you are using? so we can be aware too, 2fa is indeed important for security, you should use it on the web or any platform that supports the feature. You can not delay transactions that have been made if your assets have been sold, what you can do is secure the income that has been sold.

Using more security is a great way to keep your wallet safe, although it's actually really annoying to have to go through several processes to make or execute a transaction. On my exchange account for example, I use not only PIN but also 2FA to make my crypto assets safe from hackers.

Sorry to hear about that, that's why there's 2FA and any other authenticating service to give an additional layer of security for our assets.

Yes, the culprit will have a hard time withdrawing your funds if there's a 2FA required to access your funds. But what is this wallet that you have? Do you remember those websites where you've logged or file that you recently downloaded?

Even if you activate the 2Fa security now, the transaction which have been carried out on your wallet cannot be un do, the only good news their is that such can't repeat it's self.. 2Fa to me is one of the most advanced way of securing crypto assets in most exchanges, but one things one need to know is that even with the 2fa activated on your account, without carefully being managed, I just discovered off recent that the google 2fa can be clone and duplicated to another device which is a perfect way for someone to clone your app and use the same security u think it's best protected to move your funds out.  

Setting additional 2FA is an additional ways to secure our wallet or data. because if we are using the 2FA, at least, we need to get access to the 2FA at first before succeeding in the transaction.
However, I cannot say that using 2FA is also the safest way because it is not guaranteed. sometimes, the hacker also has a way to trap us and get our 2FA code to access our wallet or platform. So, it means that in the online world, there is no guarantee of 100% safe.
But at least, setting 2FA is better than not, to avoid such bad thing, at elast we are trying to protect our assets better

Adding 2 fa in your wallet means if you are adding more layer to access your money. Im sorry for your lose but you must have learned a lot from this case if 2fa was a really important thing despite some bad cases about that but mostly 2fa was still useful for the users to keep their money securely from the hackers. I think that even majority of members in here are also using or activating their 2fa to keep their money securely without any risk to be stolen by scammers. This is the most important part when it comes to secure your money.
You must make it available in your wallet to make sure hackers will not able to access your wallet easily without knowing the code from your 2fa

It is important to not create expectations that are out of place, 2FA is safer than to not use it but hackers are incredibly resourceful and if they have targeted you specifically they can wait until they can break your 2FA and hack you anyway.

The great advantage is that it makes getting to your coins more difficult and it can help you to notice that there is something wrong and tighten your security before you lose your coins, so whenever possible we need to enable it but we must also remember that no system is 100% safe.

Supposedly if you activate 2FA on every transaction or your wallet, something like that shouldn't be able to happen, but if it's a decentralized wallet and can be opened only with a private key then 2fa will be useless because such a wallet can be used in many applications such as Metamask, so what you pay more attention to is the security on the Private Key that you have so that it cannot be stolen from the contents of the wallet that you have.

2FA is a must whenever something related to money is being done. This increase the security of the application involved. Nowadays most of the Exchanges and gambling platforms keeps requesting to add the 2FA to increase the security. I don't get the way by which OP's wallet have been breached. It looks like someone who is close to him or known about his wallets have used it an opportunity and sold his holdings.

Even if this is done by a Known person, there'll be traces. OP has to cross check the transactions and he might get some clue on the same.

i am sorry  :'(, but transactions that are already in progress cannot be postponed or stopped.

2fa is very useful for increasing wallet security, so i always use it to add another layer of security to my wallet.
my advice, you should still use 2fa and PIN to avoid this kind of thing happening again in the future.

there is no guarantee that it will be one hundred percent secure, but 2fa is the highest security to protect our data today, 2fa is also almost mandatory to use for all exchanges. For them, the main high security is 2fa, so far it has been proven to reduce the risk of data or asset theft. I have proven it myself, as long as our account access or 2fa access remains safe in one place, I am sure our assets will be safe, so far I have never lost any assets or sold assets myself, because I always install 2fa in my every exchange account.

It was compromised already. Probably someone either got access on your email and able to do some transactions. If you install 2fa then he cant get to access it however, Im not sure if your funds will be safez since he already got access to it and you dont know what other things malicious he sent off so your account can still be access regardless you put a 2fa.

if your assets are already transferred, then there is no way to stop it.
2fa and PIN are the initial security used to avoid account breaches, so they are very important and recommended. although sometimes a bit complicated, but that's okay. nowadays very many hackers can penetrate your account if you don't use 2fa or PIN. by using it, at least you can find out someone is trying to get into your account, and you can take precautions by changing the password. preferably, after this, you need to use 2fa and PIN as the first security for the account you choose. That's why banks are really tightening this up, because it's quite a sensitive issue at the moment, moreover there are so many hackers who are targeting someone's account out there.

when the transaction is running and the TXhash already exists, the transaction cannot be canceled. but in the future you have to be more careful, always use a PIN and 2FA. if needed use a phone number for authentication as well. like i did on my binance account, i activated all security without exception. You are too negligent in this, that's why your account/wallet was hacked.

2FA was a very important thing when you are storing your assets into application. If you are using only paper wallet and this doesn't need but when you are storing your assets online or in app and activating the 2FA was a must for you. You have been learned a very important lesson and you must always aware if 2FA was helping people so much to secure their assets from the hackers. I have been seeing people were activating this important thing after their wallet got hacked. You must not repeat your mistake again. Try to always activate 2FA when it was available.
This is the most important thing in the wallet and it's your money but about the security of wallet.

I think you got hacked by someone by phishing. And they did it easily because of your security lack  And that's because you didn't enable your two-factor authentication security system. There is no such thing as an automatic sale with 2fa. I think they hacked  access to your account and have been transacted or withdrawn from your wallet coins. From then on, keep an eye on these and enable the security systems well.

I believe that getting access to a wallet via a connected platform or through private keys will neutralise every form of security on a wallet? Correct me if I am wrong and that includes 2FA Authentication itself, unless the wallet is a centralized wallet that implement 2FA for every transactions but won't be possible on the likes of trust wallet, coinomi wallet and metamask.

I always activate 2FA on the exchanges that I usually use, and I think it's proven to be more secure, maybe in special cases someone will be able to enter but to open or hack 2FA is in fact very difficult, so always enable 2FA for the security of our assets.

for more details what wallet did you use at that time?
and are you sure it's the fault of the wallet you're using?
try to think again what you did before your wallet was hacked?

for example I use a mobile trustwallet, and I've never had a problem like yours even though my wallet is without 2FA. maybe you have tried swapping token dusting in your wallet? if yes, this might be the problem. next time don't care about any tokens in your wallet, unless you bought one. or do you know where the token came from.

yes it is, and you know that's a bad news mate because your late and your assets is completely gone, so its impossible to recover or whatsoever.

for me having 2fa on my wallet for long time now, so far i didn't see any suspicious activity on my wallet , that's why i'm very confident that having 2FA is totally secured and no one can make transactions without a code..
So i suggest better to create new one then set up 2FA to prevent losses, stop using that wallet again!

When having huge amounts of crypto assets, it's understandable that people will use all the necessary things to secure it because we all know that hackers are there and scammers are just looking for some opportunity to strike. That's why 2FA authentication is important because you are maximizing your security to protect your assets from hackers. Many investors skip this kind of thing because they thought they were just safe in their preferred exchanges while they are completely prone to such a kind of tragedy where they cannot be saved by their exchanges.

We can't say it was 100% safe as there is no such thing as an online wallet. However, this gives us at least the highest level of protection. But before using this stuff, be sure you have the backup codes as in case of the loss of your phone or damage to your computer, there still a way to restore and access your wallet.

All of my wallet and accounts from exchanges had captured the 2FA security which was recommended and I could really say, for how many years my funds are safe. I really suggest you do this but of course, don't let other people use your device as this is one reason for code leaks.

Once the transaction is done, there is no chance to delay or cancel the transaction by applying 2FA or PIN. You should have set 2FA for your wallet in advance. It gave your wallet an extra protection. I don't think it's safe to use this wallet anymore. Better open a new wallet and set 2FA prior to use it.

Dude, you should've learned more before making a wallet because that will be like your vault. But you did it like leaving the vault just closed but was not even locked with a security key.
That's 2FA when it comes to wallet. Your security key or better because no one could access it except you who own the email and the phone. Even if they hacked your e-mail they will need to input the restore key which you only have.
A good learning point. You know what to do next.

No, it's not possible to delay the transaction even if there is or there is no 2FA the function of the 2FA is to protect anyone from logging in not to prevent them from doing transactions it's better to use pin and 2FA to avoid intrusion, but on Electrum you are required to input your password when you ar doing transactions, you did not post the kind of wallet you're using but if there's an option to put pin or 2FA you should do so.

You should protect your wallet with the 2fa authenticator, it's a risk if you're not set up your 2FA because something like this can happen especially when you're entering a phishing site without realizing it. When someone enters your wallet usually the user will receive a notification in their email and you can change your password because 2FA is hard to break through. Always keep your wallet safe

I do not want to upset you my friend, you have already lost your funds. And you won't get those money back. It was necessary to first register on the wallet to use all the means of protection that will protect you from scammers in the future. As the saying goes, we learn from mistakes. And next time you will know how to use protection in time to secure your funds.

Nothing is secured in online, i'm using crypto.com where implemented biometric verification that's means it’s highly secured exchange but in 2022 (January) this exchange got hacked and lost over 30 million dollars. But i'm inspiring to use 2fa or others security to safe your wallet. But what's wallet you're using right now? I'm using Trust Wallet for long time but i didn’t use 2fa and i didn’t face such issues.

That's why we people use 2FA and PIN at least we know it's not easy for hackers to break all this easily so these extra security measures keep one's wallet safe from hackers. No, now it's not possible whether you activate 2FA or PIN but I must say be more careful now use 2FA and PIN in every wallet and avoid clicking on random links.

When you are using any exchange it is necessary you use 2fa and PIN to be on the secure side, you would hear many hacks and yet i am wondering why anyone would not understand the seriousness of securing their funds. The fact is there is no point in holding thousands of dollars worth of fund if you are not intelligent enough to secure them :P.

2FA is not used to secure your wallet.

Hackers can use different methods to hack your wallet or account by managing 2FA code from you.

2FA is used to make sure that whatever happens is due to your intervention. That is, it is used to authenticate you.

If you are not smart then 2FA will not make you smart, it is not a very rare case that many people have been deceived by sharing 2FA with unknown person for their greed.

Is it even possible to create a wallet without any protection at all? I mean every software that you can use to create a wallet be it on ethereum, BSC or whatever other chain asks you to set a password yourself or gives you a seed phrase or a private key that you need to write down. Without the seed phrase or key no one can import your wallet to any other software. If you haved used an app or a browser wallet or exchange then you should also have a password for that app or website which you need in order to access your wallet or account that you have there. Of course the more security steps you have the better so if you have amounts >10$ somewhere, i would take the time to enable 2FA.

I guess every exchange is required to safely use the code from 2FA and this PIN is a required protection in the exchange but why doesn't he do it?
Although there's no guarantee that it's accurate but I think with 2FA and PIN combined it's safe not to run into issues like this or he might have been neglectful to interrupt something like that.
I hope he can use this method.

I have been using 2fa since the day my funds were stolen. If it weren't for this app, I would never be using exchange and other sites that requires pw with your valuable in it. So far after using this security measures, I have never been experiencing issues of of funds being lost, so I consider it to br safe.

It is always advisable to add additional security features to any wallet to ensure that it is more secured, considering high sophistication of hackers, some wallets are 2fa enabled especially any one that is linked to your mobile phone network such that before any translation is carried out a 2fa must be triggered in such a way that any anonymous transaction or if the wallet is being compromised it can easily be detected, however I don't think a PIN is needed here, it just to protect your wallet from being accessed by close friends, relatives e.t.c.

Using 2FA and pin can at least increase the security of your wallet but it doesn’t mean you’re invulnerable, hackers know how to decode so better not to trust any links and don’t ever download any files from unfamiliar emails, you still need to be careful. Sorry for your loss and maybe you can try to use hard wallet next time to be more secured, this can still be one of the most secured wallet to store your crypto.

Using 2FA and PIN is a strong bulwark of wallet security because there is no history of hackers successfully cracking 2FA and PIN access from other mobiles, that is to my knowledge. That it is necessary to protect the wallet take advantage of all the security features provided to protect the assets in the wallet.

2FA regularly used by people to secure their wallet. The hacker will have need to fill it to be able to access your wallet. This means when you are wanna accessing your wallet and you must also put your pin as well. In my opinion if this is the strongest security to secure your wallet from the hackers. That has become a new standard when you are wanna trying to save any amounts from your wallets. I think that people are also using this security measure for their wallets.
If you are not using this and this is a big question for you whether you care with your money or not.

First of all, when you login in your account, you put gmail and password. This is not enough for secure to your any account. After that, you set a 2fa(google,sms,gmail code etc.) and this is not 100% secure. I suggest you that you put very strong password and set google authenticator.

In my opinion, it is very helpful in the context of security protection when you make transactions, either deposit or WD. but I'm a little confused by your statement "all my assets were sold automatically" because if I'm not mistaken, almost all transactions are always asked to enter the 2Fa code when you are going to make any type of transaction as I remember the code is in the user's hands.

2FA is considered the safest way to protect all accounts today such as email, social networks, wallets, etc. Unfortunately for you since you have not enabled the 2FA function for your wallet, this is a very serious omission.

2FA can still be hacked but it is not easy and not every hacker can attack and steal your 2FA code.  Nothing is absolutely safe, but protect your assets in the best way.

Theoretically, a mobile wallet can be hacked using phishing, SMS interception and 2fa, using fake ads or changing the clipboard. Online wallets and services often rely on SMS and 2FA for an added layer of security for users. However, hackers have found ways to intercept SMS and 2FA by gaining access to the code. This can give them access to different accounts. Reliable and one hundred percent protection, I think does not exist. What app did you use?

When the transaction especially withdrawing certainly needs at least 1 confirmation, even though we do not activate 2fa but when withdrawal definitely requires confirmation in an email when registering, and if we activate 2fa, of course the account position is stronger because I rarely hear the theft case on users who activate 2fa.

The more options you use to secure your account and protect your funds, the more secure your work will become. And in this regard, 2FA is one of the simplest and most reliable means of protection and, accordingly, you do not need to ignore such a function.

confirmation code that send by activating 2fa could help us for unexpected condition such as hacking case , we could protect our account with 2 layer protection if maybe our email hacked but the another security still secure by us. google auth or sms code be lastest protection if hacker access our account, no one could access it except our self.

You did not come back to tell us what wallet you are using, obviously, there's an intrusion could be your computer is infected or there's someone who knows your private key or passphrase, even if there is a 2FA or pin he can always transfer it from another wallet.

Your assets are gone already there's no way to get it back unless you know the owner of the wallet where your assets were sent,
its a lesson learn and people should be aware of intrusion from virus infection or from intrusion into their computer or cellphone
Take all the necessary precautions to implement all the necessary security.

I'm not sure but I think he's referring to his wallet possibly on an exchange, which is a non-custodial wallet as most of today's non custodial wallets don't have a connection to 2FA. If we use non custodial wallet our assets will be stolen by virus or hacker as you said.
But storing assets on centralized exchanges, it will be an unacceptable omission if he does not have 2FA or pin enabled. Hopefully OP will come back to tell us where you hold your assets.

activating 2fa really important for us since we save alot money in our wallet. without securing our wallet , it is very risky for us to lossing our money. hacker have many technique to access our wallet, maybe they sent unknown link or even sent unknown token in wallet . when we unconcious accessing it , they automaticly have a key to access it. and google auth or sms code could prevent this accident. no matter how much our money , its an obligation now in several exchanges to activate it.

I can't say totally safe because I think there are still hack cases that are reported and those accounts are already secured with 2fa's but still it's better than not setting up a 2fa. This way you will get alerts if there is someone that tries to access your account and they can't easily access it not unless if they are pro hackers but I think pro hackers only target accounts with huge money inside but I don't think you hold millions and billions of dollars in your account so you are likely safe from them.

It can cause delay but that's fine as long as you are now extra protected. Laziness should not be an excuse to set up 2fa's on our accounts.

2fa and pin is an additional protection for your funds that's why it is necessary that  you always enable it. Hackers are always there waiting for a victim specially those account which is not secured and easy to hack. Be responsible to your assets/funds..always use a trusted wallet apps or even a crypto exchange.

That's one of method to increase the security for your wallet. I don't know what do you think about that since you didn't even protect your wallet use 2FA as an additional security for your wallet. This doesn't make sense at all. I think that you have a reason why you didn't put 2 FA in your wallet. This is pretty weird for me to see someone who didn't even know if 2FA was exist to secure his wallet. I hope that you will learn a lot from your case. Your wallet needs more protection from the scammers.
This is a must for you to keep your wallet safe.

Every security system has some weaknesses and nothing is able to ensure complete security. However, the 2FA security system plays an important role in protecting your wallet and account. This makes it almost impossible for hackers to access your account and extract assets. It is possible to easily protect assets, especially from incompetent hackers or those who seek to intentionally steal assets.

Everyone should use sms or 2fa or gmail code for the security of his own wallet. I am also use sms or 2fa or something else. By the way, if you do stop limit or something do to sell your token, that will happen automatically. I use stop limit in exchange wallet so that it is sold automatically.

I honestly think that it heavily depends, if the things that got stolen are private key 2fa is pretty much useless but if you are using the wallet like the ones that didnt really reveal its private key then activating the 2fa could be pretty much your lifesaver.
then maybe you can take this as conclusion only using wallet that didn’t really reveal its private key and also have the feature of enabling the 2fa there are plenty of wallets like these that usually are being provided by the bigger platform.
other than that just use more secured wallet like trezor and ledger bro if you think your assets are big enough.

Sometimes it can't be a safe way too. It's too increase the security for your wallet. I meant you can't totally pegged with your 2FA to make your wallet being secure from the scammers. You must also become dicipline to avoid to deal with any suspicious link that spread by scammers on internet.
There are bunch of scammers and adding 2fa was also a good choice but your activity can become the reason why your wallet get compromised. It may if you are clicking on the phishing link or doing bad thing that makes your wallet get compromished.
You must learn from this.

Well, in the crypto industry, nothing is safe and secure because we have seen lots of hacking examples of decentralized. So, if decentralized accounts can be hacked, centralised accounts can be hacked as well, but if we can use all of our wallets, we may gain some security as well. To get security, we should enable all the security options on the wallet or exchange, like the biggest number of passwords, SMS verification, pin setup, email verification, and the most important 2FA security of Google authoticator. And for this, we should use a backed up Google authoticator so that we won't lose it. And yeah, 2fa adds an extra layer of security to our fund. I hope now you understand. Thank you.

it doesn't make sense, if you look at the incident, because the token input is from the wallet, it's not very clear what wallet is being used, and the txn hash link doesn't exist, it's difficult to study, if it can still be resolved, take immediate action, and if the asset has been sold  other than your token pair, you can secure it immediately, but if it's in your wallet like metamask it won't happen there must be confirmation from metamask first with your password, but if it's in another wallet, at least it depends on you how you take action, if in exchange, it is very important 2FA google authenticator, and verification via email, be smart in protecting your assets.

It can be delayed or even failed when you are using 2fa to give more security for your fund. If the scammers unable to put code from your 2fa and your wallet can't be opened and it will be safe. that's why all of exchange sites are also giving notice that activate the 2fa has become a mandatory for all of users. As a personal wallet user and then you should learn what already done by exchange site to make sure the funds owned by the users are safe. You can activate your 2fa soon and you will be seeing your code will be a key to enter into your wallet.
Hacker can't hijack your wallet easily without using the code from your 2fa.

It is very important that the hackers don't have clone access to your phone where your 2FA app has been installed otherwise they can still breach access to your wallet. That is why I highly recommend not to put together your wallet and 2FA authenticator as this will guarantee to put the safety of your funds as these hackers won't have the chance to get the PIN. I have been using this for several years and was proven enough.
Well, you can double security by adding email confirmation (but this gives hassles to us ).

You can imagine when it's the same like you are adding the big wall for the scammers to be able to take your funds. So, adding the more wall will be very important thing i believe. So many people are even adding more and more layers to their wallet to make sure their wallet will never be hacked by the scammers. I think that you do understand so well about this. People this time even doing anything carefully caused by they have been learning from their past experience or even from others who got the same mistake like that.
Move on and add another wall to your wallet and scammer will not able to touch it again. 2fa is the most important thing for now.

I like that way of setting example, 2fa is a wall, another layer to protect your wallet from any potential hackers. Installing that and

keep it to protect your wallet is very important. The more you understand how it works, the more you will continue to add new layers of

protections, it's something that shows how careful you are with your investment. As long as you kept your phone where the 2fa was installed,

you'll have the additional keys for your protection.

I want to believe you are not new to crypto and wallets and should have known better to use both most importantly or at least one like the 2fa. I have my 2FA on a device I hardly connect to the internet just for extra security. Sorry for what happened but again I don't think those crypto-assets can be recovered.

It's the safest way for you to keep your wallet safe. Im feeling curious about what thing that makes you didn't interested to use 2fa just like others. I do believe if you have friends in the crypto and your friends are also using it. If you are not still interesting to use it and the big question for yourself about are you interested to secure your wallet or not. If that's not safe and bunch of crypto users will not activate their 2fa verification to make sure their accounts are having strong security.
I think that that if this is a common standard in the cryptocurrency.

Using 2FA can really be useful to secure your wallet but I think some people and hackers still can managed to bypass the security but I haven't experience anything so far and I make sure that I enable all of the 2FA of my accounts that can be supported by 2FA.

Perhaps, we can't deny that it gives protection to our wallets. However, this is not the only way it guarantee a total safety to our account/wallet, it still depends on us. But what really I can say is that the use of 2FA authentication to filter possible unpermitted access to our account makes you feel easy and gives less worry that one day these hackers will crack our keys/password. For I could say that for many years I was using this, I was safe and had no experience of being hacked, and that was because I set my 2FA for my security enhancement.

If your 2fa got leaked and it can't delay scammer to take your money from your wallet but if your code was totally safe and it will prevent scammer to take your money from your wallet. You must also know the difference between it. Remember that sometimes if someone can still be hacked even when he was having 2fa as his 2fa already leaked. Security was a very important thing but the most important thing is about how can you secure your wallet in the safe place and no one able to take your data to open your wallet.

First and foremost, which wallet do you use? Since you've mentioned 2FA and it involves a mobile number, that would be a centralized wallet. The thing is if you have set an "easy to remember" password and didn't enable 2FA, it would likely lead to our crypto wallets to get compromised and having our assets drained as the hackers would initiate the unauthorized transaction easily.

In all of my centralized wallets and exchanges aside from the password, I also have 2FA, pin, fingerprint and Google Authenticator as we needed extra layers for protecting ourselves against these unauthorized transactions.

It is really unfortunate that it has come to this, but with scammers and hackers all over the market the truth is that even when you take all the precautions necessary that you may think sometimes you feel as if you have not done enough.

And this is because we know what hackers are capable of, and despite all of those protections they only need to find a weak spot on the system that you use to protect your coins and one day you could wake up to the fact that you lost your coins, this has never happened to me but it is something that can happen if you are not careful enough.

Using 2FA is a good layer of security and protection, but the thing is that the criminals can bypass this one as well. It seems that they are always one step of the game because they were able to get access to you account and unfortunately take all your hard earn coins. So I would say though, it's better than nothing, and you should protect your account with 2FA such as Yubikey.

2fa is a must. I can't imagine someone using an online platform while dealing with medium to large sums of money without protecting the account with 2fa and email confirmation for transactions. It's just a very simple and easy step, but that makes total difference, without any doubts. I don't even know why passwords still exist, since they aren't enough to avoid hackers accessing your accounts. They don't protect anything and can be easily discovered by the most basic hackers automatic tools. Always make sure you are using every security measures and features the website you are signed in have to offer to customers.

It will absolutely be safer if you add 2fa, but actually if you have the wallet that's not store your private key, it should be save even without any 2fa / pin. Since I don't know what wallet you are using and how your accident happened, the 2fa, pin or anything won't matters if you recklessly spreading your private information.

I would say 2FA acts as an additional security layer over your assets but it didn't provide any sort of guarantee because if you have enabled SMS 2FA then it's risky but if you have some TOTP 2FA enabled then it's far better than conventional way as you have different codes at different times.But be sure to have safety at your end also because everything is prone to hacks and loss if you are careless enough for it.

So we should not be too careless using the phishing links that have been circulating now.
Because even though there is strong security, if we are trapped in a phishing link it is useless and we must quickly take action to secure our assets to other wallets.
‌

That is why it is very important to enable 2fa for whatever kind of wallet app we are using. That is our only way of securing our funds so no person should just ignore that 2fa features of all wallet apps. All wallets that I have used, I always ensure the maximum security the app can offer either 2fa, sms verification, email verification and etc. to secure my funds because once the transaction has been done there is no way we can get them back. So there is no way you can recover your money even after enabling your wallet app 2fa. I feel sorry for you mate, hope you've learned your lesson now.

Right, i think Google 2fa authentication is more secure than gmail and mobile sms code because gmail can be hack any time so it’s definitely a bit risky, i faced some issues with gmail security, so i don’t think only gmail is enough to protect your wallet. I feel safe with 2fa authentication but also it’s not 100% safe, hackers can pass it also.

Really sad you didn't use two factor authentication {2FA} so secure your funds. Please going forward don't joke with the usefulness of the power of 2fa. Many people have fallen victim to hacks and the only way to prevent hackers from having access to your funds is by securing it with OTP or 2FA.

Having 2FA in your account or your wallet doesn't mean that it is completely safe. 2FA can be hacked by hackers if you ask me but having 2FA will increase its safety  compared to not having 2FA in your account or wallet for non-hacker person. For example, I got your account in an exchange site where you have funds in there when you are trading but if I log on your account, I can't actually access it since the site ask me to provide a OTP for 2FA. That's why 2FA works for those who doesn't know how to hack.

As much as possible it is best to exhaust/use available security measures to protect your assets especially in exchanges. Though PIN and 2FA may not always be a perfect security system but it is better than not using it. Your assets are what you have worked for and deserve to be protected. If applicable, also use a mix of complex alphanumeric, etc. to create passwords. It is like making things hard for yourself, but it is preferable than to have the experience a stolen fund.

2FA is a good security but if you fail to protect it then your account can still be compromise.
On most of my important account, I always have my 2FA and of course there's also a back up to that so make sure you do note of that and keep it on a safer place. We are living in a market that is very vulnerable to hackers and scammers, we should use every security that we can use here in the market and in your online accounts.

Hacking does not have to come from online, it might be through friends and someone close also through use of unsecure WIFI etc. As much as it is kept online one should be careful onground. If you lose your phone having the same number and email access open, such individual might be exposed already, many more cases

Obviously as what others mentioned in here, there is no direct connection between 2fa and your usual crypto transaction so no, OP.
Since the transaction went through already, I would be more concerned on the current device that you are using since the hacker could possibly more damage which I hope I am wrong. Either do a virus scan or clean install of your device.
Start from there then start implementing 2FA and PIN if you really wish for an extra layer of security.

This is a sad way to bid farewell to one's hard earned cash. I don't know why some crypto enthusiasts will decide not to password their wallets. Isn't it like having a bank account without setting up a password for it? It sounds wrong. Even if you don't feel the need to set up a 2FA for it, you should at least put a pin or password to it. You don't need to make everything very easy for a thief breaking into your eallett. A strong pin should give the thief some sweat exercise before they crack it open. Sorry about your loss. Sadly, there's nothing else you can do on that now.

as far as I use 2fa there is no security that can be penetrated by hackers, because the security code will always change every 5 seconds. Every wallet and exchange I use must use 2fa , always recommended by them, I'm sure you should install this, although there are always loopholes, but I never lost while using this.

There is no direct connection if he didn't set a 2fa but if he sets it then there is a connection because before you log on or do any transactions, you will need to enter the 2fa code that will be sent in your mailbox or phone number.

You might be right that his device is already infected by some malware or viruses and it's not safe to use it anymore. He can do some scanning, hard resetting the phone or completely logout all his accounts and transfer to a fresh device and next time he will need to be more careful on what he was dealing with. Who wouldn't want to have an extra layer of security? Unless if he don't care that his funds will get hacked one day (which already happened). I bet he changed his mind now.

2FA so far are the safest option and yes it changes all the time but it can also be compromised especially if you fall for a hack attempt asking for that pin. Its good to always use the security option available on that wallet, don’t hesitate to use it because its for your own good and you have the money to protect, better to be safe always.

That's really bad but whenever you are having fund in a wallet you should always make sure you protect your wallet very well. You using 2fa as your security is a good idea because it's going to improve the security of your wallet, before anybody can access your wallet they will have to input one time code with expires mostly after 30 seconds. Am not saying using 2fa guaranty maximum security but it will increase your security level.

Indeed, it was been highly recommended to all as this will enhance security aside from email verification.

As a fundholder, thinking about the security of our money is our top priority. We can't underestimate hackers by now as the more careless we are, the more we give them a chance to have an entry. Like to expose your address that holds a huge amount is not a good idea
but with the 2FA protections gives them a hard time cracking it.

Surely there is no 100% guarantee that we use 2FA it will be safe, if we aim for long -term investments, the best thing is to store assets in private wallet, do not store assets in exchanges because if we are busy then not logged in for a long time then our assets Can be lost and when they want to log in again they ask KYC and many reasons.

One mistake or one reason for the hackers to penetrate in your account for sure they will grab the opportunity right away.

Cases of hacking can only be avoided by the owner itself, by doing your extra securities in your wallet or in your account will give hackers

hard time to deal with you, 2fa is another layer that can give you good protection. You should adopt and install this feature to tighten

the security of your wallet/account.

Long term or short term investments that's doesn't matter when you own a decent amount of money then i think you should buy a hardware wallet (i'm using safepal wallet from the last year) to keep safe your assets. Keep store your assets on the exchanges it will never safe even in the top tier exchanges.

Maybe have different thing when you save assets on crypto wallet exchange market like Binance, Houbi or Kucoin. When detecting with access log in different IP have confirmation to your email account, but I think you loss controlling maybe save assets on wallet like Safepal or trustwallet and Metamask. Better if save assets on exchange market, use 2fa and you fund keep safety, actually when have some one hack your account and change password you have change with one days for withdrawing suspend and get back access to your exchange account.

I think the problem in your case is that someon has manged to stea or clone your simcard information and managed to reset tje authenticator as the firs thing they do is send you an email and send you a phone message.

I don't know if you remember the time that Binance was hacked, one of the things for which it was hacked and almost everything stolen was because they managed to find the 2FA codes and from there everything was very simple, I don't know how they would do it but at that time They only talked about hacking, so it can be said that nothing is safe, even in a wallet, be it electrum or another, it is more viable that it has more security, a private key or the set of phrases because the 2fa already had its vulnerability, then based In this, it is not to be alarmist but I prefer to have the 2fa password sha256 and why not, another layer of security.

I am wondering which wallet you’re making use of, but I can guess that whatever wallet it is that you’re using would be an online wallet or possibly an exchange, which is not fully safe.

As for making use of 2FA, I believe that two factor authentication can really be helpful in securing your account, as it wouldn’t be as easy to penetrate as someone who has only activated just a password for their account; having PIN and 2FA activated would create a double layer of security for your wallet. But I would recommend that you switch to making use of a trusted wallet, and more likely an offline wallet.

I think once you set the PIN and 2FA, then you will be able to secure your wallet for next transactions.
It is very important to set the PIN, or at least the password on the wallet you use.
Im currently using Trust wallet and secure it with my phone authentication like password and finger lock.

If you are using AUTHY, I could say its a safe one dude. I had been using it for 4 years now and so far so good, I never encounter any problem with this app. Unlike, google authenticator apps after a months using it the code became invalid. Unlike for the AUTHY is not happening the same as google authenticator apps. Believe me this is proven and tested already. 

One of your wallets you said, I am guessing you have managed to leak your private key one way or the other, my first question is are you a airdrop fan at one point in time? The second question is what platform are you running your wallet on? Mobile or PC? And the third question is what wallet are you using?. As for your question, 2FA has no power to secure your recovery seed or private key, once they are leaked your 2FA is powerless.

well, we don't know whether it can be delayed or not, for sure, the defense of your wallet is stronger than that, and it is possible that your assets cannot be sold automatically because of your PIN and 2fa.
this is a lesson for all of us to continue to use the full security provided by the services we use. as far as I know, hackers will more easily access the assets that we have if there is no PIN and 2fa. So, when you have a chance to activate it, then activate it immediately. it would be great if there was an additional pin from the phone that we have. Always take precautions before things go wrong.

In fact, even exchanges are asking to enable 2FA authentication for safety. This is really necessary as you holder, we can't be sorry right because of our negligence, we can't just say that hackers aren't smart. No, anticipating such a thing is a good example that we care much about our money and we dare not to let these people take control of our hard-earned money. And besides, this is not a hard thing to do, we can just do it in a few minutes and be done, however, this gives us higher security for the lifetime.

Some exchanges really made it compulsory, if you don't comply with the 2FA, you can have a notification from your email or confirmation from the transactions you are making. Nowadays, we cannot be too complacent, hackers are so smart that they can even hack even the most popular and secured exchanges, so we have to ensure we had the best security to protect our assets.

Nothing can be guaranteed to be 100% secure and uncrackable, but an account activated with pin code, 2FA and authentication from email address, it will be relatively safe for our assets. Hackers can attack our accounts but if we turn on full protection layers, hackers will take a lot of time and then maybe they will have a chance to handle it in time. Cryptocurrency investment faces a lot of risks besides avoiding scam projects We must also keep our accounts away from hackers at all times, so enable all security functions as much as possible good.

Understand this right now if you haven’t yet, ignore anyone tell you about complete security in anything it’s false, there is nothing that can offer you that in Crypto-currency. With that said you also have to understand 2FA is a strong security approach than many has tested and trusted to provide a good security enhancement/backing, so if you are looking for ways to add on to you being always security sensitive then 2FA is a good addition for you.

If the transaction is in progress, then you can cancel via email, or without confirming the ongoing transaction. 2Fa and PIN are very important in an exchange, if you don't use them, it is very likely that transactions can be made, because there are exchanges that can make transactions without passing an email confirmation. I think you understand this very well, because you have been on this forum for a long time, and of course have used many exchanges to trade.

All transactions that have entered the system and processed transactions cannot be changed unless there is an error in the blockchain so that the transaction will be canceled automatically, you must be more careful in interacting on the internet so that your device is safe to use. Even if the transaction is 2fa enabled, if your private key is not stolen it is still very safe to do, but if the private key is stolen, it is better for you to replace your wallet with a new one.

Although using 2fa security may not fully guarantee the security of our assets but at least linking the 2fa security code can keep our wallets from being hacked, because usually when we want to make a withdrawal or a new device is detected trying to enter our exchange account they will asks to enter 2fa code and if the code we enter is wrong then the exchange will suspend us from making withdrawals within 3 days or a week.

2fa Secure is being used in every way to keep the account secure because hackers cannot easily hack through it enabling two factor security code 2FA will help increase the security of your account. This code will be used each time for account login withdrawal creation etc and can freely switch to SMS verification mode.

First of all it’s important to let other people know about the app in which this thing happened to you.
Secondly you should always remember that when you have some good amount of money in any wallet or exchange, then you should always use 2 Factor Authentication.
The work of 2FA is to let you know through an alert or asks you for 2nd time confirmation whenever you try to transact money.
It doesn’t delay the process, rather I would say it’s an extra layer of security which is very appropriate in this crypto industry.
Sorry to hear about your losses.

2FA is an option to make your wallet/account more secure on the other hand makes it more difficult to be hacked. But it is very difficult to say that it protects your wallet/account every time because it fully depends upon you and the conduction in which you are using it. But in my opinion, it is a good habit to use the 2FA system in your confidential login every time.

2FA is too effective in providing an assurance of security for most users. I was also having a hard time securing my funds before but when I started using 2fa, I feel more confident in storing my funds in my wallet. It's actually a struggle for more hackers because they can't hack wallets easily when 2fa existed. It may take a little time but you only have to secure your mobile number or email for the verification process.

In my opinion 2FA is very safe to use, because many exchanges also apply it, we as users must implement it,
but indeed one of the obstacles is when 2FA on our handphones is lost, it is difficult for us to manage it, this is the problem,

2fa and pin both are very important for a wallet even you should hide private key from everyone. This is an internet world where you will not get accurate information from anyone so you have to put your money in the right place and have tight security. The hacker group will always try to deceive you so you have to protect yourself from everything especially the wallets where the security system is strong.

Having double security in our wallets is very important, especially if we use third party applications, we can do double security such as fingerprints and other security such as verification of mobile messages before making transactions, you can also do this because security in the wallet only we can manage and if we are careless while surfing the internet then our data can be stolen or even lost from your device.

The use of Hardware wallets is better than hot wallets, and both do not require 2FA, it's just that some wallets require a Pin for transactions.
If you are using a wallet on an exchange, all you have to do is protect your account with 2FA, and don't tell others about your PIN, 2FA clone code and recovery phrase

I recommend storing your crypto investments with cold wallets such as Trezor and Ledger, or at least SafePal. And it is desirable to additionally protect with multi-signatures the possibility of transactions

The same thing happened to me once but I sense I revealed my private key somehow, also the name of the wallet is coinomi, I later learnt that this wallet isn't as secure as trust wallet and other popular crypto wallet in the space, try using more popular crypto wallet and stay away from free offers or airdrops.

If we set 2fa on the wallet we use for every transaction here and other accounts we have, it will be very useful for our security so I think 2fa is very important for us if we use it.  We will get a lot of security here.

2FA is an extra layer of security.  I think everyone should apply it for all wallets and accounts. Because it will protect our wallet and account but it will not harm the wallet and account. So why don't we use it?
Even if you lose your handphone, you can recover your 2FA code if it is backed up. For example, if you save the QR code to import your 2FA code on google drive or somewhere else, you can import 2FA code later even if you lose your phone.

How can you reveal your private key of your wallet? Is this because your wallet is leaking data, or is it your own fault?

You think using trust wallet is safer, but this also depend on you. how you make your device more secure. You should make sure there is no virus in your device, if your activity is still not use and internet with safe browsing or installed app without checking permission request, then your account on trust wallet could be leaked. so, be careful.

Not every popular wallet is secured though. I would say that even my own local wallet sometimes blocks me out as I did not have complied yet into their KYC policy and it is quite annoying not gonna lie.
I don't think offers or airdrops itself would impact your security at all unless you were easily baited to a phishing site which what happened to me back then.

If I'm to choose between coinomi and trust wallet, I'll use both of them but will use most of the time Trust wallet. Also, the amount that I'll be putting there won't be that much because that's my first rule when it's about these wallets.
How can sort of revealed your private key somewhere? It's your practice that you've shown your private key to anyone and that shouldn't be done by yours.

We really need to set up the 2FA on our wallet for best security indeed.
I often heard about people losing his phone and the coins in the wallet are gone already.
Without 2FA, we will be vulnerable against hacks when we lose access of our wallet.

There's no doubt that 2FA increases the security and control measure of the asset or account that uses it.
The issue about the safety of the asset due to the possibility of 2FA being compromised is another insight that should be thought through.

No, it's not safe. There is always a risk if the transaction is wrongly addressed. However, if the phone is damaged or we can get it back by saving the FA2Code, you can always set it up again in our wallet.

It seems like hackers are trying to steal and collect your digital money from your wallet by being hacked, especially if we connect Metamask and it turns out that the website token is a scam, our Metamask funds can be siphoned off like a dusting attack in my opinion.

Yeah for sure 2FA is safe in every way. it's secure your wallet by adding one extra step to logging into your Wallet/Account. 2FA is actually adding an extra layer of security to your Account/Wallet.
For the following Reason, 2FA is best for everyone
* Adding an additional layer of security to Account/Wallet
* Blocking hacker attacks automatically
* Secure your Account/Wallet rather than somebody knowing your password
After my studies at google, I discover that some new studies say that 2FA is not safe and
are being hacked and not using an intervention from the user. The assault is known as "man-in-the-center" but am not sure about it is the truth or lie.
ref: https://screenrant.com/two-factor-authentication-security-effective/

The cryptocurrency business is like Banking industries, as we see in our local environment, which every taller service customer care or cashier have it OTP, (One Time Password), for enable them to login into the given platform and also carried out transaction from one point to another. Having said that, it also applicable to a crypto wallet, which we have many wallet to store our Digital Asset, which you did not mention the platform your operating to store your asset. Therefore is very good to add and additional security on your wallet by Applying 2FA and PIN for a security purpose.

I guess that transaction is already gone but it is important to always have a 2fa enabled in all your wallets apart from your pin too. There is not too much protection with your crypto assets. Regardless of whichever wallet it is, whether exchange wallets or other non-custodial wallets which are even regarded to be safer still I think we still need to have different levels of protection.

It looks like the victim of  "man-in-the-middle" accidentally clicks a phishing site that looks like a mirrored image of the target site.  That way the user sends information to the phishers database then the phisher sends the data to the target website.  So it is basically the owner sending information of his account to the phisher.  Not the 2fa being hacked.  No matter what the security in this scenario is, it will not prevent the phisher from logging into his account when the owner tries to log into his account.

---

Anything that adds a layer of security delays a hacker from breaking into our accounts. Email verification, 2fa, and mobile verification can increase the security of our accounts.  Combining them can synergize the effect.

You should use 2FA with pin for transactions for full safety in your wallet. For using 2FA you should use extra phone by use 2fa aps. Although if you have completely all process then hacker can't hack your wallet. Even one plus point you need to avoid all fake message from your gamil account and never click any link.

No security system is 100% perfect, there will always be loopholes to steal, hackers always think 3 steps ahead, this is what makes many companies pay dearly for security systems, and of course developments will continue to occur so the idea of ​​using retina eyes is a solution for a better security system.

Nothing is 100% safe, but to protect our assets we should use the best asset protection methods and 2FA is considered the most effective solution today.

I also usually enable security features if it is available like 2fa, email, sms even prevent login from strange IP. This cannot guarantee 100% that my account will be completely safe but if hackers attack and try to take control of my account, they will take quite a while and I can react in time.

Yes, 2FA still has an exploit in which victims with 2FA devices got compromised and exported their master key to the other or hacker in this case. This requires getting victim's device hooked and compromised which is very hard but still not 100% impossible, especially if the victim is careless.

2fa with mobile phone confirmation or email login code is the safest way for me. You can use 2fa alone but that leaves a lot of room to improve the security of your account. By pairing 2fa with an email login code or mobile phone login code, you'll have more leech way.

yes of course it is very safe, if the exchange platform requires using 2FA then use it,
because indeed 2FA will make your account and funds safe there,
we know the biggest enemy of the crypto world is only 1, namely hacker attacks, and 2FA will protect you, I'm sure that

It is very important that all access that we consider important has security using 2fa because by using this system the possibility of our assets being stolen is very small so we will feel safe and calm when storing many assets on the platform. And seeing your case that you have lost tokens because the transaction has been carried out, you can only sincerely do it.

I use a lobstr wallet, I activated 2fa, but maybe  it's true that you said something was wrong when I activated it, most likely the intruder had entered before I installed 2 fa
