What if the bank abstained from evaluating your own stuff, and instead provided you with whatever they consider a 'good' device? Like a powered-up version of the TOTP hardware tokens they used to provide 15 years ago.

Instead of negotiating over what you do with your own devices, when you open a bank account they loan you a small, cheap, ultra-locked-down phone-like device that only runs the bank app and biometric verification. You may still use a web interface for online banking if you want a bigger screen and keyboard, but regardless all transactions need a confirmation through the bank's device.

This way you're free to do whatever you want with your hardware (including even not having one!), without requiring every bank to support every possible platform under the sun.

That's a nice idea! My main bank still provides one of those little TOTP devices to this day.
