I write this for all of you that visiting this post, not just for newbie or beginner.
Lets just straight to the point, you need at least 3 different email addresses.
1. For exchanges / social media account and any important account. Don't share this email to anyone else, please make sure that only you know this email. If someone knows this email address they will try to hack your account, even if you have 2fa on that exchange it will likely make your account lock, and if this your social media still probably fuck you up though.
2. For work/school. This means professional email, don't give it to anyone besides your college worker or friend from school.
3. For spam/promotional. You will use this email address for anything else, sign up for a newsletter, etc.

Why I wrote this post? Not long ago almost all my exchanges account got hacked, not really hacked tbh, just someone tries to reset a password something like that. and that because I use the same email for almost all my account and my email listed on my blog.
You also need to read this post by Ux PSA: DO NOT USE THE SAME PASSWORD FOR DIFFERENT SITES! (https://bitcointalk.org/index.php?topic=5165708.0/) and this by ONEnergy revealing e-mail might be dangerous (https://bitcointalk.org/index.php?topic=5165361.0/)

You can say that manage more than one email can be a hard job, so use this mail.com service you can create one main email address and add up to 10 more alias email addresses for free. That means you have 10 email address in one account. just remember don't use the main email for login to mail.com to any other sites, just use the aliases provided by them.

I would never put those two in the same pot.
I think your exchanges and wallets should have their own email. They are part of your financial information and almost as important as your banking, credit card and other financial accounts. I say almost as important because I also think that crypto and non-crypto related financial information shouldn't be
together.  

Social media on the other side has ads, promotions, remainders and other stuff that you could click on but you shouldn't mix them together with your crypto exchanges or wallets.

I have never been hacked before but high level of spams from different websites/social media using the same registration email made me diversified them. It's similar to yours, 3 emails for 3 categories: seriously important, important and normal. Those emails are divided into yahoo mail, gmail and outlook mail; passwords are also different.

Completely valid point. Hypothetically lets say you have a work email, which you also use for your finances. Due to your work email being your business contact, it will be easily connected to your online persona, anyone who gets a hold of your email will know exactly who you are in the real world. This becomes a problem because when you are stripped of your anonymity, you become more vulnerable to different forms of online attack, such as targeted phishing, doxing and extortion, if your pockets are big enough you may even be vulnerable to being simswapped/having the port out scam done on you.

@OP Another useful thing you might wanna include is + tags.
+ tags are essentially a way to make 1 email in to many.
If I register for a service, lets say coinbase on the email Ux123@gmail.com (Not my actual email), then I can't register another email on that.
By using + tags, you can, If I wanted to register another account, I could simply register it under Ux123+coinbase@gmail.com, it would recognize it as a seperate email, but all emails from coinbase in regards to the account registered on the +coinbase tag would still be delivered to me. Using + tags also makes it harder to find out if its actually your email or not, because more often than not in forgot password forms, you have to enter the email. If I don't have a coinbase account on Ux123@gmail.com but I do have one on Ux123+Coinbase@gmail.com, simply inputting UX123@gmail.com in to the field in the forgot password form will give any matches or send an email, meaning unless the account that the hacker has attempted to acquire was on a social network that was freshly breached, they won't even think you have a coinbase account.

Hopefully I was able to actually get my message across, I haven't slept in like 2 days.
Anyways, great point OP.

Sure, it also can work that way. And that's why I say you need at least 3, if you want to have more than that is absolutely fine and even better IMO. As long as you were capable to manage and not use one email for another.

and make sure not use the same username between those email, I mean it kinda pointless if TeQuiero@gmail.com TeQuiero@yahoo.com and TeQuiero@outlook.com right.

Completely new to me will try to learn this first, and thanks for your info mate.

Absolutely this. I mean, you should probably just avoid using social media altogether, since all it is good for is mining your information to sell to third parties and negatively impacting on your mental health. If you absolutely have to use it, then it should be with an email completely separate from all things crypto related. Why would you want every exchange, ICO, airdrop, bounty, whatever being able to link your online crypto activities to your real identity? And why would you want everyone you connect with on social media to know the email you use to log in to crypto accounts? That is terrible for both privacy and security.

Why you need too many emails as long as you can enhance the security of your account through certain services such as 2FA or google authenticator.
Wallets do not need emails, so the platforms and financial services must be connected to secure emails and then use an offline phone to ensure that the e-mail is not compromised/hacked.
Creating a lot of e-mails requires the inclusion of a phone number which greatly weakens security.

Well, it's good to have an extra email addresses for when you're signing up for services or newsletters that aren't exchanges or work-related so your main inbox is kept as clean as possible and there's a minimal amount of spam in the main inbox you have where you're keeping things for exchanges and emails for other important sites. Ideally the email you're using for other signups doesn't have as much sensitive information on it, so you don't need as many security measures on that inbox.

Or you could go full nutcase like somebody...(whom I always see when I look in the mirror)

I nearly have one email account with a different password for each important service.
Furthermore, that is only from my standard chrome browser as I also have two portable versions that I keep around for thigs I deem more dangerous or which are heavily customized for plugins and blocks.  ;D



Why would in the first situation a phone be secure but not in the second?
If you use a throwaway sim (which in my country you must load with at least 1 euro to not lose the number) it's as safe as it can get.

Sim swap is not possible against prepaid phone cards.

According to me there should be more than 3 email.

1. To Exchange and wallet.  And for social media sites like FB, twitter and LinkedIn.
2. For low quality or new exchange sites. New social media and app sites.
3. For professional and school work.
4. For bounties and airdrops.

Passwords should be different for different site. Everyone should write passwords in notepad but not real passwords must change few words which you remember.
For example you used password: "123456789" then in notepad write "123456987"
 

Linking email addresses to phone numbers, especially multiple addresses to the same number, is just another way to compromise your own privacy. There are plenty of privacy conscious email providers which don't require a phone number. There are even free ones. ProtonMail is probably the most obvious choice, but you can look here for others: https://prxbx.com/email/

Again, no. It isn't smart to link your social media and real life identity to your crypto holdings, or to display the email you use for crypto to all your social media friends or followers.

Don't do this. Use a password manager such as KeePass, which will encrypt and store all your passwords for you. Storing your passwords, even slightly altered, as plain text is a massive security risk. If someone steals that file, you have made brute forcing your password many orders of magnitude easier as they can now just try variations of whatever you have written.

FYI "work emails" are pretty much given by the company you are working for, they either have a separate email system or use privacy based email for their work so if you are employed then you don't have to worry about this. For self-employed on the other hand its a best practice for you to separate your emails from your business to your other emails. Aside from the privacy and protection it's a simple solution for you to have an organize and efficient way to communicate with your business.

Using or having more than one email at different purposes is a common practice even back then. Honestly, I considered that practice as part of our "common sense" when dealing in the internet world.

Back in the days where I first explore the internet world, I don't encounter any warnings, suggestions or prompts like that but decided to do that. It's just that I hate spam emails that's why I decided to make another email and used it for other purposes. If you guys remember back in Yahoo! days, they have a group site where conversation can be sent directly to email and you can reply there on the spot without going to Yahoo groups main. I was annoyed at hundred of emails everyday and I missed important emails.

My different emails are being used to:

-Personal Email (family, friends, workmates, etc.)
-Social Media
-Online Games (it's a must for me as a Gamer and for multi-accounts)
-For crypto web exchange, I used 2 different emails for local and global.
-Business/(for mobile banking or any related service ).
-Work email (limited only to my workplace - I just listed it but honestly, can't be considered as part of my own email)
- etc.

This is not a good idea, you shouldn't write or save them anywhere and especially not in an non-encrypted way. 
I have read about people saving passwords in their browsers as well and this is also an unsafe method. Those passwords are stored locally on your computer and if you get infected by a password stealer they will search the locations where these files are kept.

Or if you still want to save your password in notepad at least compress it to rar/zip and get that file a password as the main protection.

 This is an example of how that strategy, in a similar context, may go really sideways for you:   how likely is to correctly reorder 24 words seed! (https://bitcointalk.org/index.php?topic=5158659.msg51607882#msg51607882)

To summarize the above thread, the person in question stored his 24 word seed in an email draft. The draft has the 24 words in plain text, but having swapped a couple of them around. Although the case is not 100% clear, it looks like someone got access to his email drafts, and tried a couple of obvious permutarions of the 24 word seed, allegedly being successful in the event.

This is a good thread.  Lots of nice info.

I suggest  multiple emails and multiple cellphones.

I have  3 tracfone's

1 for really important 2fa or authenticator accounts.

1 for less important accounts


1 for bs.

None can post here as my bitcointalk account is simply too important to me to lose.

I have multiple emails.

I have multiple core wallets with cloned backups.

I have multiple trezors.

I have 1 coinbase account with not much in it.
I have very little coins in a few exchanges.

Quite simply security is a bitch.

Hey! I also do this! :P

Just a tip, you can pay great alternative email services like Protonmail[1] and Tutanota[2] like $1-$5 a month(depending on what service), and get multiple aliases to your emails. So you simply don't need to switch emails every time you want to check messages from other emails.

But yea you can just simply create multiple Gmail accounts for free if privacy isn't an issue for you.

You can use your other email to set it as your recovery email when your email has been compromised. We won't be able to know or predict when your email will be hacked or lost. It can be hacked any time if you are too careless with your secret information. Example situation where you have three emails let's just name it email 1, email 2 and email 3 then you will use email 2 to as email recovery for email 1 while email 3 as email 2 recovery email and last email 1 as email 3 recovery email in case you forgot the details about one of your emails.

I have tried this once to be honest and the results are excruciating for me because I need to switch into different emails every time one service asks for authentication and I'm logged in on a different email... It might not be the most efficient way to sort things out and to not get all your fruits swept if one has to get your basket but then again, it works, and it works perfectly for me. Never have I received something suspicious in services which I frequent, specifically those related to my crypto accounts and finances as well.

But then again, there's ProtonMail, though I'm still not familiar on how they work so I guess I'll stick with my 21 emails.

Our personal security is top priority, being cautious are required and we don't want to compromise everything once we get hacked. As what the elders always said "don't put all your eggs in one basket"

Having organize email accounts and multiple crypto wallet are best practices to follow.

If you're having problem to remember every password for every account, you may use password manager.

To name a few,
1. Keepass
2. Dashlane
3. Enpass
4. Passbolt

don't forget to backup your password manager dbase.

Most people get lazy and end up using the same password for all their accounts or one that is very similar.  This is a huge mistake and you should be willing to put in the time and care to have very different passwords that are complex unless you don't care about your personal information.

More emails do not make sense and actually do not increase your security and safety. If people don't have healthy web-surfing habits, more emails don't help them safely from potential threats, from bad guys. This is another thing beside inconvenience when someone have to log in different emails.
However, using few emails that store important things, and only for your main accounts (with main parts of your capital) is enough. Such emails should not be used for any other things. For example: Email A for exchange A should be used for only Exchange A.
Note that should not store your money on exchanges, if you don't have plan to trade or sell your coins.
21 emails are too many, and you should not expand it.  ;D
I don't know reasons of repeatedly email hack of this guy: https://bitcointalk.org/index.php?topic=5165936.0
I guess that guy has unhealthy web-surfing habits (I maybe wrong)

This is risky, and depends entirely on which archiving program you are using, and what version of it you are using. Many archivers, and certainly older versions, don't actually encrypt the data before slapping a password on the archive, making it fairly trivial to break in to. If you really want to save them in notepad and encrypt them yourself, then you should do so on an offline computer and using proper encryption software such as Veracrypt. Bear in mind that even if you then delete the notepad file with the passwords saves in plain text, they will still be stored on your hard drive and could potentially be recovered by an attacker.

The safest option for most users without the technical knowledge to do this properly is to use KeePass or similar as initially suggested.

Well this a very complicated issue. What of whereby you've already have your main email giving out for exchange and you're using it presently in every cryptocurrency registration. Should it be right to start deregister them and put another email.

If you mean by "deregister" is changing the email. Yes, done that.

Or just like I write at the end of my post. you can use mail.com services. It's completely free, and you can get up to 10 aliases address in one email. The downside of this method is if the main email address that you use for login got compromised that means all of your email gone, so make sure that one email for login only for login and you never use it for something else.

I haven't tried those other password managers, I use to use dashlane but to restore you need to buy it. SO I use the inbuilt chrome one and it works just fine.




I have used 7zip and it can encrypt in sha256. I wonder if that is the same sha256 as bitcoin mining and if a miner could crack it some how?  :-\
The ultimate backup you should use is paper. Best backup and last resort. You can asso use OCR software to scan it to make things easier when transferring it to digital form.

It is better to have more than one email. There should be one for school and work related stuff. Another one for bounties and another one for airdrops. You van use the one for bounties for exchange sites too or better still create another one for that purpose.

For personal use, an email must be separate from others. On the other hands, if you are a bounty hunter and airdrop participants, you must use a bulk email for that.
Better you use the personal use for exchanges because exchanges sometimes send very important update which you must keep track.

I use more than 5 emails and i used to get mails about someone trying to have access to my exchange account but I'm less worried because i use a very strong password for my mail and im very careful too i don't want to end up falling for phishing links

This is the most important thing that we should be aware of, email password even not so complicated is not gonna be hack easily, I have use a simple password in my emails and it has not been hack yet, of course I don't hope it will but I see the big risk here is when we get phish.

Thank you for sharing, I am doing so. I only use my official email to serve my business, not my email address. With any website, I use the emails I create to avoid spam emails and malicious links sent via email.

Upon reading all the posts, I realized that I have some security flaws especially on how I manage my emails, I realized that it is really okay to use multiple email addresses, because before I am just creating those emails for nothing or just getting some free signup bonus on every website over the internet in a website like in social media.

I am starting to create my new email addresses, like fresh accounts, it's just sad because I already some of my emails on existing websites I used which I barely can't remember anymore, but it's still okay, as long as it is not important.

I am highlighting the yet in your post. You have not been hacked yet but what if you get targeted in the future and all you had to do to prevent the hack was to use a stronger password?! Add a few special characters and numbers, big letter here and there and the strength of your password goes up from low to strong.
