I can only hope they will revisit face unlock in the era of face masks. I greatly prefered fingerprint unlock. I treat either of these as tamper resistance rather than actual security, but I find fingerprint unlock to be a much better experience.
Even before face-masks, I found that my Pixel 4 can't recognize me with a bike helmet on. I have a phone mount on my handlebars and fingerprint-unlocking is very convenient (not while moving, obviously). Also if I'm driving, I can hand the phone to my wife and finger-unlock it without looking away from the road, which is definitely not possible with a face-unlock.
