This is stupid face id unlock with watch, when mask is on, does not work if Wifi is off. Found this out the hard way.

Fine your right!
Though sometimes it still does not work. Even with it on for some odd reason.
I never have wifi on when out of the house. I don’t see the point of wasting the battery
modern day turning on wifi doesn't drain your battery anymore, it's just a receiver and uses no measurable power (less than 1mw)
However, turning on improves your GPS accuracy, allows you to airdrop, handoff also enables the new Apple Watch unlock.
So why not?
This “stupid” attribute is part of what keeps this method of authentication secure.
I’ve never turned wifi off on any device except when I’m in a location with very slow wifi service and want to make sure the device uses the faster cell network. No battery issue ever unless a particular app gets stuck running, rare but it happens.
