How to use Pixel 4's Face Unlock and Motion Sense features (bye, fingerprint scanners!) Google ditched the fingerprint sensor, but you can unlock your Pixel 4 with your face instead.
Although it scans your entire face, the Use Face ID With a Mask feature places an emphasis on authenticating the unique features around your eyes.
To unlock your device using facial recognition, simply raise your device to wake it up and look at the screen. The device will automatically recognise your face and unlock it.
