New Android Theft Protection Feature Updates: Smarter, Stronger

Posted by Nataliya Stanetsky, Fabricio Ferracioli, Elliot Sisteron, Irene Ang of the Android Security Team

Phone theft is more than just losing a device; it’s a form of financial fraud that can leave you suddenly vulnerable to personal data and financial theft. That’s why we’re committed to providing multi-layered defenses that help protect you before, during, and after a theft attempt.

Today, we’re announcing a powerful set of theft protection feature updates that build on our existing protections, designed to give you greater peace of mind by making your device a much harder target for criminals.

Stronger Authentication Safeguards

We’ve expanded our security to protect you against an even wider range of threats. These updates are now available for Android devices running Android 16+.

More User Control for Failed Authentications: In Android 15, we launched Failed Authentication Lock, a feature that automatically locks the device’s screen after excessive failed authentication attempts. This feature is now getting a new dedicated enable/disable toggle in settings, giving you more granular control over your device’s security.

Expanding Identity Check to cover more: Early in 2025, we enabled Identity Check for Android 15+, which requires the user to utilize biometrics when performing certain actions outside of trusted places. Later in the year, we extended this safeguard to cover all features and apps that use the Android Biometric Prompt. This means that critical tools that utilize Biometric Prompt, like third-party banking apps and Google Password Manager, now automatically benefit from the additional security of Identity Check.

Stronger Protection Against Screen Lock Guessing: We’re making it much harder for a thief to guess your PIN, pattern, or password by increasing the lockout time after failed attempts. To ensure you aren’t locked out by mistake (by a curious child, for instance), identical incorrect guesses no longer count toward your retry limit.

Enhanced Recovery Tools

We’re also enhancing our recovery tools to make them even more helpful. This update is now available for Android devices running Android 10+.

More Control for Remote Lock. Remote Lock (android.com/lock) is a crucial tool that lets you lock your lost or stolen device from any web browser. We are adding a new optional security question/challenge to the process. This helps ensure that only you, the real device owner, can initiate a lock, adding another layer of security to your recovery flow.

Proactive Protection: “Default-On” in Brazil

Keeping our users safe is a top priority, which is why we’re working to make theft protection available out-of-the-box for more Android users. For new Android devices activated in Brazil, two of our key theft protection features are now enabled by default:

  • Theft Detection Lock: Uses on-device AI to sense motion and context that may indicate a “snatch-and-run” theft. If a theft attempt is detected, it will quickly lock the device screen to help protect your data.
  • Remote Lock: Allows users to lock their device from any device that provides a web access to android.com/lock without the need to have enabled the feature in advance.

This helps ensure new devices have a critical layer of theft protection from day one.

Continuing To innovate in Device Theft Protection

We’re always evolving our protections to stay one step ahead of thieves. Our ongoing updates help ensure that no matter where you go, you can have greater peace of mind knowing your device and data are protected by Android’s multi-layered defenses. Keep a lookout for even more Android theft protection updates.
