Face ID Alternative Appearance
In the iOS Settings.app, there is a Face ID & Passcode > Set up an Alternative Apperance option. I tried it with my mask on, perhaps it might be able to recognize an alternative appearance, as that’s what it is, to me at least.
Unfortunately I got a “face obstructed” message, which is completely true, as the lower half of my face is obstructed by the mask, of course.
Well, I had to give it a shot anyways.
