To confirm, if you hit "Lock iPhone" on your watch, the next time you swipe up on the phone to unlock, it requires your passcode. Did this five times in a row, and the passcode was required every time, with or without a mask on.I updated the phone, then the watch, and I noticed something. I unlocked my phone with a mask on, then I hit "Lock iPhone" on my watch. The next time I swiped up on the iPhone to unlock it (without a mask on), the phone asked for my passcode. I wonder if hitting "Lock iPhone" temporarily disables FaceID? I'll keep playing with it.
