Google ditched the fingerprint sensor and instead went with facial recognition on the Pixel 4 and Pixel 4 XL. If you didn’t enable Face Unlock during the phone’s setup process, here’s how to configure it from the Settings menu.
To get started, swipe down on the home screen twice to expose the quick settings tiles. Tap on the gear icon to jump into the Settings menu.
Alternatively, you can swipe up on the home screen to view the app drawer. From there, scroll down and select the “Settings” app.
Next, scroll down and tap on the “Security” option.
Before you proceed, make sure you have a screen lock enabled. If you don’t have a password, PIN, or pattern set up to unlock your Pixel 4 or Pixel 4 XL, you’ll need to tap on “Screen Lock” and follow the on-screen instructions.
With your handset now secure, tap on the “Face Unlock” option to set up the facial recognition feature.
Your phone will now explain how Face Unlock works along with a warning that the feature works even if you’re not directly looking at the device. Tap on the “Next” button to proceed.
The Pixel 4 will now walk you through how to hold the phone and rotate your head while setting up Face Unlock. Select the “Start” button to start the setup process.
Select the “Setup for Limited Vision or Head Motion” option if either of those things pertains to you. Doing this will provide you with more accessible instructions for setting up Face Unlock.
Follow the on-screen instructions for setting up Face Unlock. Continue rotating your head until all of the blue boxes have disappeared.
Once complete, Face Unlock should be set up and ready to go. Hit the “Done” button to jump out of the installation process.
You can now test Face Unlock by hitting the power button and locking the Google Pixel 4 or Pixel 4 XL. Tap the display or press the power button again and watch the handset unlock almost instantly.
