iOS 14.5 Developer Beta 1 is out today and with that comes a long-awaited feature. In iOS 14.5, Face ID works with a Face Mask if you are wearing an unlocked Apple Watch.
The feature, first noticed by Joanna Stern, requires an unlocked Apple Watch on your wrist for Face ID to unlock the iPhone. This feature must be manually enabled in Settings. Apple Pay payments still require a full Face ID scan so this new method will not suffice for Apple Pay.
