How face unlock works

Face images are used to create a model of your face, and that model is stored in Pixel’s security chip on the device. No images or face models are ever sent to Google. The face images aren’t stored.

When you enroll in Pixel face unlock, the face models are used solely for face unlock. Your face model doesn’t go to any other Google services or apps.

Important: 
  • Looking at your phone can unlock it even when you don’t intend to. 
  • Your phone can be unlocked by someone who looks a lot like you, like an identical sibling. 
  • Your phone can also be unlocked by someone else if it’s held up to your face, even if your eyes are closed. Keep your phone in a safe place, like your front pocket or handbag. To prepare for unsafe situations, learn how to turn on lockdown.

Fix problems with face unlock

I have trouble with setup

  • When you try to set up face unlock, wear a typical outfit in a typical place you use your phone. For example, if you wear glasses or a headscarf every day to your job, set up with those on at work.
  • If you can’t move your head well, you can still set up with limited mobility. Start face unlock setup, and then tap Setup for limited vision or head motion.
I have trouble with face unlock
Sometimes for security, your phone won’t unlock with your face. You can still unlock your phone: 
  1. While your phone is locked, swipe up.
  2. Enter your PIN, pattern, or password.
If your phone regularly has trouble with face unlock:
  • Hold your phone vertically, directly in front of your face, about 20 cm away.
  • Use a soft, dry cloth to wipe the top of your screen.
  • Turn off your phone, then back on.
  • If you wear accessories, like a mask or dark sunglasses, take them off. 
  • If you’re in bright, direct sunlight, move to the shade.
  • If your phone has a screen protector, remove it. Your screen protector shouldn’t block your phone’s infrared cameras. Learn where the IR cameras are.
  • If you change your appearance, delete your face data and set up face unlock again.
