Currently, one can choose to log in to the Android app using 2FA, but if one wants the convenience of using biometric sensors to log in (e.g. fingerprint sensor), one can only lock and unlock the app. This, however, does not allow the usage of 2FA.
Could you by any chance either implement logging in with a biometric sensor or add 2FA to the unlocking process? In the end, it would be nice if every time I want to use the app, it would ask me for my fingerprint and then for my 2FA (in my case Yubikey) afterward. This would allow combining the convenience of using a fingerprint sensor with the security of using 2FA.
