How about anywhere cold enough to require gloves, and reasonable enough to require face masks?

In those dire situations I would opt for passcode unlocking with smartphone gloves. Face ID, Touch ID and passcode, only the most extreme scenarios would need more.

That’s great. I’d prefer to use watch unlocking.

Also, these are not “extreme” or “dire” or even uncommon conditions - most of Northern Europe, Canada, and the north-eastern USA experience several months of such conditions every year.

Iris auth on Galaxy S8/S9 was great but it's gone.
