Bitcoin Forum

 I think I found two great videos on youtube on the dos and don'ts of password creation.  A real must watch. I encourage everyone to watch these and then consider if your passwords are really safe.  

  https://www.youtube.com/watch?v=7U-RbOKanYs  Also  https://www.youtube.com/watch?v=3NjQ9b3pgIg

  If you don't trust my link the video is called: "Password Cracking - Computerphile" also "Password Choice - Computerphile "

 If you know of a better video on password creation plz post it.

 Edit: would also like to recommend everyone watch "How NOT to Store Passwords! - Computerphile" and "Security of Data on Disk - Computerphile"

I just watched the video that you provided. It is very educational and provided me good knowledge about password cracking. I know that we should be very careful in creating passwords and making it very hard to crack is a top priority but I didn't know that with just the use of 4 hi-end Nvidia graphics cards, passwords of million of people can be cracked in just a few seconds. It is an eye-opener for me. I will re-evaluate the status of my passwords because of this video. Thanks man for posting this up.  :D

The amount of entropy storeable inside the human mind is to limited. You are well advised to carry some sort of jewellery / ornament with you that keeps the secrets. Which book has that been taken from? I am remembering Stephenson's "Cryptonomicon" but it has been another one of his books.

The best way is to randomly generate your private keys (paper wallet etc) so that even the owner can not remember. This will not have the problem of having unsecure addresses, like those generated using brainwallet.

Just use a password generator, select a huge password with lots of symbols capitals numbers and you are good ! for now at least... because there is the golden rule saying what it locked it can be unlocked,

No one gonna share their password to anyone. If you do a mistake like keeping hard password and logging in to the site same like blockchain other wallet site means also your funds will be taken out by hackers. Please make proper log in attempt and keep safe private key and don't share your DAT file of tour wallet this enough to be safe.

When you see the number of people here who get their bitcointalk account hacked, it makes me wonder how they deal with their bitcoin activities, online banking ect... A weak password is surely the main reason, but it's not hard to make a strong password and of course not use the same with every site

People don't take the security seriously as they should and that is the reason for so many hacked accounts and wallets, malware infections and other security breaches. But some of them are not well informed how important is to protect your self so this forum could also be the place to raise awarness.

I think what is always underestimated when it comes to setting passwords, though, is the importance of having different passwords for different services.  Most people have passwords in hundreds of different things, and if your password for a less secure service is the same as your password for a more secure service, it doesn't only matter what that password is - the hacker is going to hack the less secure service, find your password and use it to get into your account on the more secure service.

See I don't think you should worry so much.
I insist you to use block chain wallet.
It is damn secure .
I use it mostly in my phone and due to safety reasons,
It doesn't even allow me to take even screenshot,
Of any of the content present in the app.
I.e when the app is open.
Talking about password ,
When I go to settings and select reset password,
They show the message that-
" Our servers have not saved your password"
So even if someone hacks the servers of block chain,
He can never know the password of our wallet.

This reminds me that I should change the passwords on my bitcoin wallets. Though it has a 2fa security and it is very long but since there are only letters in it I guess the hackers could easily hack it. My wallets are always at zero balance but if I dont place a good password on it and suddenly somebody send me a good amount of btc then that would be trouble. Next time when I will make or generate a wallet I will make sure that even I will make it very complicated.

First of all passwords must be stored in some place no matter what and second bitcoin private keys are entirely different than our websites passwords.
What I want to know is the mechanism where you provide a private key for an address how many times per second could you try a private key to see if it's the right one? if we could limit those attempts somehow that might eliminate the brute force and cracking which depends on try and errors.
I also like the idea of playing music as your password but scientists even doubt if some day human brain might get hacked.

I use cryptocurrencies's addresses as passwords and save each one with a hint of which service it belongs to and put them on a text file then create a zip file with a strong password and cuut and paste it into a usb stick.

Your videos are very helpful regarding in making safe passwords for your account and I think it is impormative but it is not that necessary for other users, maybe the newbies would see this as very helpful for them, but even if you had a bad password for your account I think to keep your account safe from hackers is to change password more often.

Maybe it is true, but not all the people can unlocked those things which are locked, and using password Generator is not that safe also because there is a possibility that you might forgot the password because of too much characters, numbers, signs, and symbols combined.

So, if you are going to use this password generator, you must save your password, for you to have a backup in case that you forgot it. Though, I always prefer creating my own password, for me to easily remember it and can't forget that easily.

If you are able to generate a random password on your own and if you could note that down then it is good and fine and it is not that easy to unlock unless and until you do something dumb.Your bitcoin passwords have to be safe and make sure your system that contain a huge number of coins are offline and i do prefer it as i do not trust any other method to store my coins.

account security is a must. but in line with current technological developments, development of how actions are increasingly sophisticated hacking. various ways being developed even though it is a criminal act.

Also using 2FA in your online wallet whatever it is where you are storing your bitcoin is also a good idea beside on using private key, and when it comes to professional hackers, there is no such thing as SAFE PASSWORD, I remember the hacking that happened in the blockchain way back 2015, where hundred of millions dollars worth of bitcoin was stolen, correct me if I am wrong.

So, there is no safe password to be honest, all we have to do is to secure our accounts and check it daily to be sure that no one is using it or already know our password.

True, 2FA is a must if you want your Bitcoins to be okay, especially on online wallets which can be compromised at any time.  If you have a password and your login isn't going through a device that you've got near you, your safety is slightly compromised.  Good passwords do help but they're not the magic solution to everything.

Well actually, password is so secured nowadays, you need to have an advance mechanics to unlock or to break passwords. But since password is so secured already, we can no longer break or breach passwords by just using crackers online. Compare it to bitcoin, you cannot hack bitcoin accounts because bitcoin is so secured already.

The way I see it, with all these Vault 7 exploits and backdoors in Cloudflare... no PASSWORD will be safe. You can have the strongest password,

and people will still spoof the site or use key loggers or swap sims to hijack the 2FA. The site should be the strongest point, but it turns out these

sites are the weakest link. Bitcoin used without 3rd parties are still the recommended way to use Bitcoin.  ;)

On the internet there are tans if advices how to keep your password safe, like to not use public wi-fi or to not use such passwords as 12345. I think it's all crap, cause hackers have all necessary equipment to open your password during couple of minutes.

I also think with the number of backdoors and exploits in online services your password being cracked shouldn't be your greatest concern. I have been using multiple services throughout the years (also non bitcoin related) and I've never had problems with password cracking. Every time someone gained access to my accounts it was through some backdoors and database hacks.
For instance I've lost access to my steam account for a couple days because some Russian hackers found a way to trigger password reset without the need for email confirmation. Of course it was before they added 2fa, but I think it also might have some flaws.

If there's a person want to know your password he can because the desirity of the person will find a way even its hard so that's reason  why it is happen. If you using password, you used a also a network which is online. And the first person could open or know your password is a developers then the hackers. The developers preventing theyre project to get negative feedbacks. So the only hack your account is that person who is interested.

To overcome this problem the best way is to just set s two factor authentication in case you are using wallet like blockchain.info while if you are storing bitcoins in a windows wallet then it can't be hacked.

By the way anyone believing that passwords can be generated please try bruteforce once and you will see how easy it is to create list with all possible combinations.

better to store them in your off line storage than having any password imho, i don't use a password i just disconnect my bitcoin from the net, and they are not hackable anymore, and leaving your coins on any website is very dangerous no matter the password you use, 2fa is not also 100% secure, search for reddit for bad story

The number of sigspammers who posted absolutely nothing useful rehashing exactly the same pseudopost in this thread gives me a headache.

This is real i have face this kind of issue when i am new to bitcoin past years, and there is no way to recover it. I am sure that so many people have fall into this victim. I think it is better for us to keep good record of our password. Yes we will keep good record of our data.

I agree with you! If you want to keep your bitcoin safe the keep your password safe. Your password is the only thing you can control as far online wallet is concerned. Some people even go to the extent of send their bitcoin wallet password to online scammers.

Thanks for this video, this is really the most issue's when it comes in online account. Because Ive heard from my friend that his account was got hacked. For me I used google 2fa indicator, so far my account was secured.

Totally agree. Most of The site owners are not aware of giving Total security to the user's passwords. So many hackings are done and we get to know that owners save users passwords in a text file without any encryption.
Regardless of how strong you make your passwords it will be cracked by hackers.

If the hacker has set a goal to crack your wallet, then he will do it. Unfortunately, there is still no such security system that provides a full guarantee that your wallet will not be hacked. But you do not need to use a very light password

That is why they invented to have an authenticator like sms 2fa that you receive the confirmation first before you can login .
This is what i am using right now because i think our bitcoin is not safe even we are using antivirus.. so for safety we need to use sms 2fa.

Bug in cloudflare is reall annoying and it can cause a big problem if you are not careful. You should always turn on the 2fa in order to well secure your account. No one wants to see the account's balance empty and money be stolen by the hackers. Remember, turn on both 2fa and phone verification, too. it is very important to save your wallet

A way to store Vault7-prooft bitcoin is I guess, creating the seed offline, then storing it somewhere physically. But I think there is increased risk in only having physical backups, you can lose them, so beware with that.

I've watch the video and it is very helpful. Some people nowadays don't consider password a big deal that is why many account are being hacked. Even a well-think password can be cracked so how about a not seriously think one. It is our responsibility to secure our online wallets and account, just like how we keep safe paper money in our wallet. Don't just give passwords to somebody, be careful who to trust these days and be extra careful in where to type your password in public.

I wanted to secure my main account as much as I could.... And one day I secured it so much that I actually lost my access to it. Half a BTC is still sitting there and will probably continue to forever. :D

Always write your password on at least 3 different places. For example, the same password on 3 papers stored in 3 different places. If you lost one, you'll recover your funds with the second. If you lose your second one too, you'll get your third one back. The third one should also be stored in a different location rather than your home! If your home ever gets burnt, you'll still have access to your money! These are extremely rare situations but... Who knows which one of us can be the victim of such a scenario!

For online wallets I think it is a bit more dangerous as they are mostly protected by a password and sometimes by 2FA.

But in other cases our bitcoins are protected by a private key which in most cases is very hard (near to impossible) to predict, and it's really hard to bruteforce it, we know how many combination are there.

How about your private keys? We know if you have the private key alone, you can access the balance of that address.

Private keys are just 52-letter passwords. They say its impossible to crack passwords this long but i still can't be sure.

I mean what if some lucky shit bruteforces my private key and access my wallet?

I think my bitçoins are safe like my password it have security to protect my bitcoin.My bitcoins are safe because im the only one who know the password and when someone try get my bitcoin he or she need the password to verified that he or she is owner.Lastly my bitcoin are totally safe like my password.
