My bank detected someone logging in with my password from a GrapheneOS phone and made me change my password and scan my face. That was dumb.
With that out of the way, and the device now seemingly authorized, it still doesn't work, because when I log in, the app restarts. That could be a real compatibility problem.
Yeah, I tried that out last year when this whole debacle was announced for the first time.
I'm not going back to paying without my phone. So yeah, I'm not going to a free platform either.
the choice really is mostly down to Google's Android or iOS - unless you're ready to make sacrifices. If you are... More power to you! I'm not (at this point in my life) right now.
