Allow folks to use a different authentication app for Google services then.

Google who?

I think that's possible already? I use Aegis for my google account authentifications.

Huh? I've been using an open source authenticator for ages for my google account. https://github.com/stratumauth/app

I've been using Keepass-XC as a 2fa using the same algorithm as Google Authenticator for years (including my Google logins); It's definitely doable already, though not integrated as seamlessly as other password managers on Android.

Did I miss some context?

I use Aegis for everything but Google. Perhaps Google is just burying the fact that you can do this. Unlike everywhere else, they verbally only state Google Authenticator.

I use Aegis for everything, including Google.

Yes you're right, it's buried. You have to choose the Google Authenticator option but they don't say it also works with other authenticator apps.

That's been possible for years now...

I've never found a single place that tells you that Google Authenticator works with other authenticator apps. They always just say Google Authenticator. And I've learned that Google Authenticator is the equivalent of Kleenex, which is a brand of tissue. It doesn't matter that it's a branded tissue. A tissue is a tissue. When I see Google Authenticator anywhere now, I immediately know that it means TOTP application.

I use aegis and a hardware key for Google. Never been prompted to use Google authenticator.

Otka on the other hand can burn in hell. How do you take a open standard and shit on it. How do you require network access for your code?

Also fuck Microsoft, I have my hardware keys registered and it only allows me to use the authenticator app. Regardless of what options I choose.
