With iPhone you can set up an alternate appearance to work with accessories like glasses/sunglasses or I assume a mask, though both might make it less secure. Personally I love Face ID. There are times it won’t work like when I’m actively brushing my teeth or wearing a mask, but those are rare enough for me and there times you can’t use Touch ID either like if you’re wearing gloves. Ideally they would have Touch ID under the screen and you could use either one.
