Feature request

Great idea to have alternative for MS solution. But right now I can’t switch on it because of fundamental issue - it requires internet connection for work and app is useless without it. It would be great to make app offline with internet only for backups

Developer Response ,

That doesn't sound right. You should be able to access your 2FA codes even when you're offline. Contact us at https://proton.me/support/contact with a more detailed description of the problem so we can have a better understanding and assist you further.

As a standalone application, it is not convenient.

In my opinion, such realization is initially wrong way and wrong concept. The Authenticator function should be a part of the Pass application and not a separate application. In this sense it is more convenient and correct in Apple Passwords. Because it is not convenient for me to run more than one application for one simple task. It is extremely uncomfortable.

The developer at Proton replied to me saying that 2FA one-time codes are already available in the Proton Pass app. I’ve been a paying subscriber to all Proton services for many years, and I also use Proton Pass — but sorry, I honestly see no such two-factor authentication features there. Nothing like that at all. Could you please point me to where exactly I can find them?

Also, I really don’t like the idea of having separate apps for passwords and another one for 2FA. That’s just not convenient. In this specific case, Apple got it right — they put everything inside the Passwords app, and it’s much easier. I don’t need to jump between different apps for the exact same task: authentication.

Developer Response ,

Proton Pass already allows you to store 2FA codes alongside your passwords, but some people prefer a separate, dedicated app. Authenticator makes this possible.

Edit: You can follow our guide at https://proton.me/support/pass-2fa to learn how to use 2FA in Proton Pass.
