The Identity Check feature has been observed on the OnePlus 13 operating with the Android 16 beta, indicating an expansion of its availability beyond select Google Pixel and Samsung Galaxy devices. This feature adds a layer of security for devices outside designated trusted locations and requires a comprehensive system update due to modifications in Android's biometric prompt code. Users can find the Identity Check option in the Settings > Google > Theft Protection menu after upgrading to Android 16. To use Identity Check, users must authenticate their identity through biometric means, such as fingerprint or facial recognition, when accessing sensitive information outside a trusted environment. The feature was initially introduced with Android 15 QPR1 for Pixel devices and is expected to be adopted by other manufacturers. It may not be enabled by default and will be compatible with devices equipped with class three biometric hardware.
