Just started subscription and created few aliases - then discovered that I can login with them, defeating the purpose.

I guess I will go back to paid Outlook subscription.

I really need this feature. Otherwise, I can’t use my Proton account the way I had planned.

Completely agree with recent comments. Long overdue. This was why I did not renew my Proton subscription. Hopefully Proton will see sense and go back to fixing the basics before launching new features.

Indeed, and this should reflect the username too. If the alias email for login is pmuv17c@protonmail.com then the username login should also switch to pmuv17c. That way, users can have a specific unused email solely for login.

It is important to use a login that is not associated with an (main)email address. This is an additional step in preventing password guessing.

Glad this is finally under review. took long enough!

I'm so excited this is under review! This is the only missing Proton feature keeping me from fully switching over to Proton for everything and ditching Microsoft and Outlook! Proton, please make it happen!

From a security perspective, it would be ideal to choose which alias can be used for log on and be able to exclude the primary address/username altogether.

I didn't realize ALL of my active addresses can be used for login until now. That's terrifying.

Login needs to be an ***unique ID***, not tied directly to an email/alias. Certainly not allowing any email/alias. Ideally, a separate login ID..

C'mon - even Microsoft allows this - I find it bizarre that 8 years after the request went in you still haven't implemented this. There's no reason to explain why it's important - just be better Proton - I just paid for a year of unlimited and can't believe I'm stuck with a system that allows any alias to log in. It's nuts.

Freakin' MICROSOFT allows this. You can disable any or all of the aliases from allowing login (well, except for one of course). C'mon Proton, you can do better here.

Wow guys, just took a paid plan. This is basic feature I'm surprised it's not implemented yet. I want to keep my login secret

This is possible on Outlook, why can't we get this option on ProtonMail?

Please allow the users choose which email address can be used to log in, so only the primary address and/or selected aliases work. As currently every alias can sign in is a major security risk because leaked or exposed aliases widen the attack surface. Most of us use aliases only for communication, we dont need that to be used for log in.

It would be really important to be able to choose which addresses can be used to log in.

Aliases should only be used to send and receive emails, not to become additional access points to my account. This way, I can use different aliases without the risk of someone exploiting them to try to gain access.

With the current system, I am forced to “reveal” my login username every time I send an email, because anyone can try to use it to authenticate themselves. If, on the other hand, I could keep my main address hidden, security would be increased: an attacker would have to guess both the correct username and password, not just one of the two.

Not even recognizing that this issue exists and just ignoring it altogether is out of my mind. Maybe Proton is not that private after all? I mean, why would a service with such wide privacy claims even be allowed to grow to such a large extent and maintain their users online safety at the same time? I doubt the US would allow that tbf. If Proton really mean that they are taking the privacy of their users seriously, I believe that the possibility to limit which email addresses can log into their users' accounts is not unfair to demand.

Perfect would be if you would have the choice what address can be used in order to log into your account -> this should be the solution to prioritize please

it could be a great way to keep the account secure, even in the case of someone accidentally leaking you email address, you may actually need to create an address just for a specific service. As i learned the hard way that a governmental service that the online registration was forced on to us and we actually need, blockes the registration with the protonmail aliases.

So in this case if you create an email for that purpose you do not want that address to be used for login in proton ecosystem. So you can have you login address always private even if you communicate the other addresses you used.
