  • WhatsApp has now added support for Pixel 8 and Pixel 8 Pro’s face unlock for its app lock security feature.
  • The Pixel 8 and Pixel 8 Pro feature Class 3 face unlock, the highest level of biometric security on Android.
  • You can use Pixel 8’s face unlock to unlock banking apps, wallet apps, and now, WhatsApp.

The Pixel 8 and Pixel 8 Pro remain some of the best Android phones you can buy these days, even though Pixel 9 fever is already reaching new highs. One of the highlight features of the Pixel 8 series is the front camera. While it’s a humble 10.5MP shooter, it features “Class 3 biometrics,” which gives a big upgrade to face unlock on these phones. You can now use this upgraded face unlock on the Pixel 8 series with WhatsApp’s app lock security feature.

Biometric authentication on Android devices falls under three classes, decided based on their architectural security and biometric security performance. This classification further considers metrics such as Spoof Acceptance Rate, Imposter Acceptance Rate, and False Acceptance Rate. Class 1 biometrics merely offer convenience but no security; Class 2 biometrics provide a basic level of security, while Class 3 biometrics offer the highest level of security on Android devices.
