I use a OnePlus phone (don't know if HN users have heard of it), and OP users rarely use the fingerprint unlock.

Although the user is definitely compromising on security, the speed of face unlock is such that it is near-instantaneous. Double tap the display, and you don't even have to blink - the phone unlocks.

It may be a gimmick in the early days of Android (think Nougat or even Oreo), but it's definitely not a gimmick now, for me at least. It's fast enough to have proved its worth.
