We do this as well, except now my wife just grabs my phone and points it at my face in the car to unlock rather than use the passcode. This works pretty easily if you have the “attention detection” feature turned off. Not arguing this is ideal, but it works and avoids retrains, although Apple have publicly stated retrains only occur if they believe the face matches above a base threshold, which makes it much less likely a female face will retrain on a male Face ID user’s phone, and vice versa. It doesn’t retrain on every passcode entry. https://images.apple.com/business/docs/FaceID_Security_Guide.pdf https://images.apple.com/business/docs/FaceID_Security_Guide...
