Google announced updated Android Theft Protection capabilities aimed at reducing account takeover and financial fraud risks following device theft, with availability starting on devices running Android 16+. The updates strengthen authentication safeguards by making screen lock guessing harder (longer lockout periods after repeated failed PIN/pattern/password attempts) and by improving controls around lock behavior after excessive failed authentications, including a dedicated settings toggle for Failed Authentication Lock.
Google also expanded Identity Check—which requires biometric authentication for sensitive actions when the device is outside trusted places—to cover a broader set of actions and apps that use the Android Biometric Prompt, including third-party banking apps and Google Password Manager. In parallel, Android’s Remote Lock capabilities were highlighted as part of the theft-response toolset, giving users more control to lock a lost or stolen device and limit further misuse.
