@AlphaLynx yes, it matches what I was thinking, the common code is available, and also the code for other systems like android and windows, but the one for Linux seems to be missing.

Maybe I'm too picky but I'll mark it as private until the proton team releases it. I'll contact them to get some feedback and put it here.

Best regards

@rsm92 I believe it is open source, as Proton says "Yes. all Proton apps, including Proton Authenticator, are fully open source. Anyone can inspect and verify our code." on their faq. Looks like it's in this monorepo, which has the GPL-3.0-or-later license, though I am not sure how the .deb is built as they do not have documentation for this.

@AlphaLynx, I think the license should be "Proprietary" since the source code is not available.

@imlostish and @JammySaga, I do not have the same issues. The sign in and device sync work perfectly and I'm unable to reproduce those bugs. As I mentioned earlier, https://proton.me/support/contact?topic=authenticator is probably the best place to report upstream issues. I'm happy to apply fixes to the packaging if I can, but these seem like problems with the app itself.

I have got the exact same issue as @Evrenos. I thought since the program was new, a few updates will fix it. No, there's been multiple updates and Proton Authenticator still refuses to sign in without any trace of error on the log.log file

Hi, I've been having a peculiar problem. On my phone, 2FA codes work correctly for logging in, but when using a computer (either exported or retrieved from device sync), the 2FA codes generated by the app don't work. Can anyone explain why this is happening? Is it a bug? Or is there something we're not understanding?

Just to illustrate this better, I'd like to give this example:

You activate 2FA on your GitHub.

Mobile generates: 648341

Now, when syncing with your computer, 2FA generates: 884621

And only the mobile code generated is useful; everything else is rejected by GitHub or any other platform... (This is currently happening to me with Discord)

@AlphaLynx login is working for me, although the UI is pretty slow at the moment.

@david-perez and all else who are using Manjaro atm: I have already reported the issue with the devs. It seems the c++ issue should be dealt with. You can either try and move to an unstable build or wait for the changes to get merged in stable. See thread here: https://forum.manjaro.org/t/c-error-when-starting-proton-authenticator/180458

11/08: the latest gcc package updates should fix the issues on Manjaro-stable.

Evrenos commented on 2025-08-05 23:28 (UTC)

@AlphaLynx nah, the log isn't showing anything weird. I'll report it to Proton.

AlphaLynx commented on 2025-08-05 21:29 (UTC)

It looks like this: https://proton.me/support/contact?topic=authenticator, would be the best place to report upstream issues
