I'm lucky my banking app works (GrapheneOS), as it's now requiring 2FA with the app anytime I login on the browser. Can't use an actually secure form like TOTP. At least they now allow passwords over 8 characters (yes, serious).

The whole issue revolves around the fact Google is presuming a device is compromised or being used for illicit shit simply because root access is possible. If they put in effort to detect/prevent the actual problems they're concerned about, this wouldn't be as big a deal. This broad punishment for simply having root access is lazy and ridiculous.
It's like if Windows apps just stopped working if they detected a local admin account. It's patently absurd to assume the ability to access anything means the device is inherently "unsafe".
