About Face Unlock

With Face Unlock, you can set up HTC Desire 21 pro 5G to unlock the screen with your face when the screen is on.

For best face scanning results

Follow these tips when registering your face:

  • Do the face scan indoors in a well-lit environment.
  • Do not cover your face with an object such as sunglasses, mask, or hat.
  • Hold your phone at face level and at a distance of 20 to 50 cm (8 to 20 in) from your face.
  • Stay still and do not move your phone while the phone scans your face.
Note: Face Unlock is less secure since your phone could be unlocked by someone or something that contains or looks like your image. If you have concerns, use other more secure authentication methods such as a screen lock pattern, PIN, or password.

Setting up Face Unlock

  1. From the Home screen, tap Settings > Security > Face Unlock.
  2. If you haven't already set up a screen lock, you'll be asked to choose and set up a backup pattern, PIN, or password for unlocking your phone. See Setting a screen lock.
  3. If prompted, choose how you want to show notification content when your phone is locked, and then tap Done.
  4. Tap Register face data, and then read the tips and reminders.
  5. Tap Next and follow the onscreen instructions to scan your face.
  6. Tap Turn on to enable Face Unlock.
Tip: By default, your phone automatically unlocks the screen when it recognizes your face. If you prefer to swipe on the lock screen first before the phone unlocks, tap Settings > Face Unlock, and then turn off the Face Unlock without swiping option.

Unlocking your phone with Face Unlock

You need to be on the lock screen to use Face Unlock for unlocking your phone.
  1. If the screen is off, press the POWER button to wake up the screen.

    You'll see the icon on the lock screen.

  2. Hold your phone in portrait orientation at face level and look at the front camera.
    • If Face Unlock is successful, you'll see the blue icon then your phone unlocks.
    • If Face Unlock is unsuccessful, you'll see the red icon. Tap it to try Face Unlock again.
Tip: If you turned off Face Unlock without swiping in Settings, you need to swipe on the lock screen after Face Unlock is successful to unlock your phone.
