Just to confirm, Passkey as 2FA works fine on desktop right?

OK, I've tested WebAuthn 2FA with Wikipedia, and found an unusual issue: I can successfully create and use a passkey on macOS 13.0 and Safari 16.1. However, when attempting to use it to login on iOS 16.1 and Safari 16.1, Wikipedia's login flow doesn't seem to prompt for a passkey at all.

Major websites like Wikipedia have yet to implement multi-factor at all

This is not a true statement. See Help:2FA. There are criticisms of the 2FA system on Wikipedia, but "doesn't exist" is not one of them. :)
