I don't see a need for a separate authenticator app when that feature is already included with Proton Pass. I mean you get both credentials and OTP in the same spot. If you really need just an OTP, just create a new entry with JUST the OTP portion in Proton Pass.

From what I've seen concerning this matter, I would advise not using authenticator apps at all. Use security keys. I would probably recommend YubiKey currently.

This would be awesome, and also be a great tool to onboard new customers!

I will dump Microsoft Authenticator for this. Pleaseeee Proton!

I would like this as well, even if the free version has no cloud backup and a cloud backup requires a paid account (as part of Proton Drive).

They could simply clone Aegis, rebrand it, implement a plugin that backs up to Proton Drive, and then add some paid QoL features.

This might be a good product idea for em.

This would be a great addition! I will dump Google authenticator for this.

Best feature.
I wait for this one to quit Google

I dont see the need for it, aegis authenticator is free & open source, plus it doesnt contains any trackers.

And, proton pass has the ability to integrate 2fa codes.

Great idea! I currently use Authy, a very functional alternative to Google and Microsoft, but I would of course have more confidence in proton.

Shouldn't this be closed? Proton Pass already does this.

Good ideas

We already have Aegis which works very well, I do not think we really need anything else at the moment

I love this if mostly free like authy but some are pay

Aegis covers this use case if you sync the local export via proton drive or other could sync you trust e.g. a self-hosted nextcloud server. Proton should not spend their limited dev time on a problem that already has a good libre/open source solution.

Doing this is a bit of a security improvement over having your TOTP codes in proton pass as they have a separate encryption key from aegis so someone with access to your proton account would still need to ***** the encryption on your aegis vault backup separately. This is less secure than Yubikeys as has been pointed out but of course less vulnerable to locking you out of your stuff if your only copies are lost/destroyed - as usual there's a trade-off.

I would like a standalone authenticator that syncs with ProtonPass for the 2FA keys, possibly secured with a hardware key or maybe a different password or something only for the authenticator to open

Integrating TOTP with Proton Pass is highly beneficial because it automatically copies the TOTP code, making it very convenient to access. Alternatively, Aegis is an open-source option.

This would be a huge thing. The danger with Offline TOTP Apps like Aegis and other are that if you forget to manually back it up, you loose everything if you loose your phone.
I know cases where exactly this happened.
Passwort reset won't help then.
But it needs to be also on Linux (Fedora).

Yes, BUT please add support for the only thing no one else is able to do: “sync” the added codes with Proton Pass so it knows there's a 2FA Code for it (without actually adding the secrets to Pass)

Why not use an open source app like Aegis which supports "indirect" cloud backup ?
No need for Proton to waste resources on such an app...
