Log in iOS

I am being driven nuts by 2-factor verification on several iOS devices, some of which get text messages, others not. None receive email much of the time. My computer gets email but not text. Logging into ring is impossible at times. My bank and credit card app allow logging in with a password and FaceID or FingerprintID (2-factor). Why can't the Ring App do the same, not needing email or text? This would make using the app much more friendly.
