WhatsApp, the Meta-owned instant messaging platform, has levelled its security service with the latest update for Pixel 8 and Pixel 8 Pro users.
Along with the Face Unlock feature for payments, Google Pixel 8 and Pixel 8 Pro users can now unlock WhatsApp's face with the Face ID feature. Earlier, Pixel 8 and Pixel 8 pro users could only use the fingerprint feature to unlock the messaging app, now WhatsApp has introduced face support unlock.

The Pixel 8 App Lock feature has been introduced to enhance user privacy and security. The Pixel 8 face unlock upgrade meets Android's highest biometric standard level (Class 3). Google credits advanced ML algorithms and Tensor G3 for making this upgrade possible. Face Unlock Pixel 8 rolled out with WhatsApp version 2.23.8.85, but there is also a server-side component.
This feature requires biometric authentication before displaying messages. On launching the app, the system face unlocks sheet will appear at the bottom of the screen with a ring around the Pixel 8 front camera. If the feature fails to recognize the face or the face is not visible, the screens will automatically return to the Pixel 8 fingerprint prompts after a few seconds.
