How can we improve our accounts settings, payments or plans?

← Accounts & payments

Only allow login with single/main address/username

Do not allow that you can log into the account with every address.

If my account name is john.smith then only allow login with john.smith or john.smith@protonmail.com. Not with finance.john.smith@protonmail.com or any other address.

Perfect would be if you would have the choice what address can be used in order to log into your account.

With the current way you have to give away your login username in order to send emails. Hiding the username from the public would be an advantage, since they would have to guess your username and the password. Not only one of them.

    It would be best to separate the login ID from the email address completely. Or allow that option for people who are especially concerned about hackers.

    It would be even better if the feature is optional. Just confuse the heck out of anyone trying to hack in!

    I'm with Joel. Usernames are part of your online identity and are not considered private.

    This is such a minimal advantage, it would be a waste of time to develop. Adding one more character to your password would do so much more to improve your security.

    I'm using Protonmail Plus. Really like it so far, but am surprised that I can log in to my account using any of my additional email addresses. The main benefit of having additional email addresses to me is, using different ones for different uses. If I don't want to give out my main email address for whatever reason, I can use a different one which I treat as a throwaway. I still see all emails sent to this address, and don't have to deal with creating a new account. What I'd like to see is that these additional email addresses can't be used to log in to your account. You should only be able to log in to your account using your main email address, which you give out to few, if any, people. This would greatly decrease the likelihood of anyone being able to try and log in to your account; if they don't have the correct email address, how can they? Thanks for all your great work.

    This is feature currently offered by Microsoft and I would love to have in ProtonMail. the idea is to be able to choose which aliases are allowed to sign-in to your account. This way, if one of your aliases is compromised in a data breach, it cannot be used to attempt to hack your email box.

    It would be good for ProtonMail too since it will not have to face multiple attempts to carck to its customers' passwords. The very first attempt would be denied.

    The idea to have aliases is submitted many times already. What I would like is that it is not possible to login using an alias and the account password.
    Currently, it is possible to login both with the .ch "username" and the .com "username", one of which is an alias. The more combinations of username and login, the higher the chances someone breaks the combination...
