Is this new, or have online accounts never offered the ability to update your email address easily?

    There are massive collections of databases online that find where breaches have occurred allowing attackers to dump the database of that service, then collect all those database dumps together to identify all known accounts under an email address. Then once that email account ever has a password breach attackers can look up and see ‘was this password used also on other accounts’ and attempt to use the same email and password on them. Moreover they will just try that email regardless of known affiliation, if they already have a user name and password across many online services, it’s safe to assume this will work sometimes. This is the essence of a credential stuffing attack.

    I’ve used abc here since I believe they write better for a lay person.

    Edit: I should mean to say, they can also create a profile of you and your many email addresses as demonstrated.

      Those are full-blown attacks from hackers, so I’m sure they could profile you from bits of data across the net.

      But if a layperson is using a different email per account, different username, a strong password, and 2fa, it’s going to be very hard to infiltrate their accounts, or even associate one account from another.

      Not giving people the option to change their email makes a hacker’s job much easier!

        Now I’m not part of this, but a international student just got scammed $170 000 dollars over 3 months. They believed that the police had seized their Australian bank account and were contacting them related to their identity being stolen. It wasn’t at the time of call, but the international student, maybe 25, was fully profiled. They knew where he studied, who they had been talking to. At the time of call, the poor kid thought he was talking to the police, gave every bit of information including bank account which had mfa, but undid it and and followed the scmmers requests believing he would be deported. He called home to his parents and asked them for more money even in order to build a new account because he believed is other one was frozen, the new account was under order and control of the scammer who this kid trusted. The scammer even made this kid move into a hotel for a week as their “premise needed to be searched” it wasn’t for a month after this that it was found because the kid believed he couldn’t tell anyone before the school (where he was attending but kept leaving to take calls which is a no no) had to tell the kid that absenteeism will result in the student visa being cancelled. At that point it all came out, month and more of being scammed.

        My point is, no it’s not business. Just look at the YouTubers, just watch Jim Browning. Just ask people, it’s a multi billion dollar industry. And it’s not limited to rules like ‘business’.

        What?! How!?

        Layperson uses same email, same username, same password and 2fa only if it is required for an account.

        Anything more and they aren’t the layperson anymore. They are security conscious that they use difffrent passwords or password manager.

        Anything more and they become paranoid (rightfuly or not, it isn’t for me to judge as there are jobs that require as much protection as possible)

        When an email is compromised, changed and there isn’t any footprint due to deletion of any suspicious activity then laypersons whole internet presence is compromised.

        Emails will keep incoming into the same inbox when there is suspicious activity, if email can’t be changed easily

          Well, I’m not a security expert, yet I do thesr things.

          Having a single email address for everything not only compromises your security, but it’s a spam nightmare.

          And having one email makes you an easier target compared to having one different email per account. It’s just a numbers game.

          A hacker or bad actor may gain access to one, but not all of your accounts.

          Most people may not be as security savvy, but that’s likely because companies don’t really do much to encourage good security practice.

          They lack 2fa, they use horrible “what’s your mother’s maiden name?” questions, and e-mail based account confirmation. I don’t blame people for not hardening their accounts when they aren’t even given good options to.

            I literally am a security expert and the only thing I change between accounts is my password, which I put in a password manager.

            With that said I do have other usernames/email addresses that I use if I’m doing something that I don’t want attached to my public persona. These can also be stored in the password manager so all is still good.

            But individual email addresses per account is overkill and a management nightmare, with a very minimal security tradeoff. I’m not exactly expecting a state sponsored attack on my email after all.

              Since I use a password manager, it’s quite easy to manage, just like different passwords for each account. No difference.

              But having different email addresses also help with reducing spam, so it’s worth it just for that.

                Yeah, but for the actual mail, do you forward the emails to one address? Or do you set up Outlook/Thunderbird to sync all of them? Manually checking all of them would be quite laborious and you might miss the occasional important email if you don’t check regularly.

                  Mail forwarding sucks. I stopped doing this a while ago.

                  My email provider handles my main email address (strong password + 2fa enabled), as well as generates temporary emails, and email aliases. Those get funnelled into my email clients, and can be disabled at will, so it’s easy to manage.

                  Someone could even use a product like Firefox Relay if they don’t have access to these features already, or want an easier way to do it. As long as the main email is protected, I don’t see any major risks here.

                  For newsletters, they go to “kill the newsletter” and I get them in a self-hosted RSS service so they never enter my email stream.

                  My password manager also generates random usernames for websites that don’t use email as a login.

                  My strategy as of late is to create a disposable, temporary password for a new site that I’m registering to. If I plan to use the account long-term, it gets an alias email (hence, one reason why it’s handy to be able to easily update my email address) or the account is simply deleted. Yes, a little more work, but it saves my sanity in the long run.

                  I’ve been going through all my accounts created in the last 20+ years and either closing them (if possible) or changing the email on them (if possible). But I did move away from gmail something like two years ago, and I’m updating any accounts that are still sending email there.

                  “Contact customer service” to do this has been messy and frustrating, as it is when I have to contact customer service to close an account.

                  The most non-essential sites seem to be the worst offenders; roblox wanted my DRIVER’S LICENCE to close the account. I politely told them to fuck off and delete the account, which they did. LOL
