Overview
- Authentication updates on Android 16+ increase lockout durations after failed PIN, pattern, or password attempts and ignore identical wrong guesses to curb brute-force attacks.
- Failed Authentication Lock now includes a dedicated on/off toggle in settings to give users direct control over the feature.
- Identity Check now covers all features and apps that use Android’s Biometric Prompt, including banking apps and Google Password Manager.
- Remote Lock at android.com/lock adds an optional security challenge to verify device ownership before a lock is initiated, with recovery upgrades available on Android 10+.
- In Brazil, new Android devices enable Theft Detection Lock and Remote Lock by default, using on-device AI to quickly lock screens during suspected snatch‑and‑run thefts.
