I use Face ID to log into my bank app. I always log out when I'm done (its also the one app I sometime force close). So I do the logout and of course I'm looking at the phone to make sure I press correctly and it logs out -and FACE ID logs me right back in - works great I guess. So I guess I will have to mostly turn the phone so it doesn't Face ID log me back in. Hadn't thought of that one before. If you don't want to log in a specif app what do you do?
