@mlanger I use it but also I know the quick way to disable it in case I'm in a situation where it could compromise me.
(Hold the side button and one of the volume buttons together for two seconds, then press the side button again once the options to turn off the phone or make an emergency call appear. FaceID will be disabled until you enter your passcode.)
@tamaaya @mlanger You can also press the power button five times in quick succession to achieve the same effect.
