Google’s Pixel 8 and Pixel 8 Pro smartphones are expanding the functionality of their face unlock feature with a significant security upgrade on WhatsApp. Thanks to the integration of Class 3 biometrics, users can now unlock sensitive apps like WhatsApp with a glance.
The advancement is powered by the Tensor G3 chip and sophisticated algorithms, and brings a higher degree of security and convenience to the Pixel lineup, echoing the capabilities previously seen in the Pixel 4.
First unveiled in 2016, Google’s Pixel phones launched with standard fingerprint sensors for secure unlocking, until 2019 when the Pixel 4 introduced advanced 3D face unlock, a feature that was later discontinued. Subsequent models returned to fingerprint sensors, including an under-display version in the Pixel 6.
Android devices classify biometric security using a tiered system, with Class 3 representing the most robust level of protection. Class 3 authentication must meet strict benchmarks for accuracy, making it suitable for sensitive applications like banking and payments.
The Pixel 8 series stands out by offering both Class 3 Face Unlock and a traditional fingerprint scanner. This combination gives users flexibility and reinforces device security with multiple authentication options.
These advancements in the Pixel 8 lineup highlight the growing potential for wider adoption of enhanced face unlock in the Android ecosystem. The convenience and security demonstrated by the Pixel 8 may prompt more applications and device manufacturers to integrate Class 3 biometrics, offering users a greater degree of protection and unlocking possibilities.
