The system works through a series of redirects. Say if I have to prove my identity to some government website, it offers different authentication methods, one of which is my bank. I 2F authenticate with my bank the way we agreed, then it redirects me back to the originating site.
Different banks offer different systems for 2FA. Most also offer an app. Google services are not always required. If you don’t want to use an app, there are ways; in addition to username/password, usually a SMS for strong auth, or some code from a database that I have for weak auth.
No app, OS-independent.
If my bank forced my to use an app that only works with google services, I’d change banks. As I did, actually.
That’s actually very similar to what we have, minus the option to change to a different bank, since all our banks are using the same 2FA app and there’s not really any other options or at least not better options. This is a very bad system, building our society on a proprietary app from a private company, but… that’s where we are unfortunately. Actually, recently our government has realized this and is developing a neutral state controlled 2FA app, but it will only run under android and iOS, so… yeah.
This also works in abrowser. At least in Finland.
Then we have different systems. How do you prove that you are you online in Finland? Do you use usernames+passwords or some 2FA ID system?

How exactly do you 2FA with the bank without the bank’s 2FA app?
