Yes, that was what I meant. The quoted passage didn't seem to include any TOTP app, including GA. Apparently they are supported, the info is just on another page.

Yeah, they don't really want you to do it. That kinda makes sense when you think about it; TOTP has a lot of friction compared to "just press the button on the device 99% of you already have linked to your account".

That makes sense for most. For me, I can have my TOTP app running on my laptop all the time. Looking around for my phone is higher friction.
