As smartphone theft continues to be a significant concern, Google has introduced a powerful new security feature called Identity Check in Android 15, offering enhanced protection against unauthorized access when devices fall into the wrong hands. This development comes as part of Google's broader initiative to strengthen mobile security across its ecosystem.
Understanding Identity Check
Identity Check represents a significant advancement in Android's security architecture, requiring biometric authentication for accessing sensitive resources when users are outside their trusted locations. This feature specifically targets scenarios where thieves might gain access to an unlocked phone or obtain the passcode, preventing them from making critical changes to the device settings or accessing sensitive information.
Feature Availability and Rollout
The initial rollout of Identity Check is notably limited. Currently, only Pixel devices running Android 15 have immediate access to the feature, while Samsung Galaxy devices with One UI 7 will receive the update in the coming weeks. Other Android manufacturers are expected to implement the feature later in 2025, signaling a gradual expansion of this security enhancement across the Android ecosystem.
Requirements for Identity Check:
- Android 15 OS
- Class 3 biometrics support
- Currently supported devices: Pixel phones and Samsung Galaxy devices with One UI 7
- Theft Protection must be enabled
- At least one trusted location must be configured
Core Security Protections
Identity Check's protective measures are comprehensive, covering crucial device functions. When enabled, the feature requires biometric verification for accessing password managers, changing PINs, modifying biometric settings, accessing developer options, and managing Google account settings when outside trusted locations. This multi-layered approach significantly reduces the risk of unauthorized device access and account takeover attempts.
Protected Features under Identity Check:
- Password manager access
- PIN/biometric settings changes
- Find My Device settings
- Developer options
- Google account management
- Screen lock modifications
Setup and Configuration
Implementing Identity Check requires several steps, including enabling Theft Protection in Android settings and supporting class 3 biometrics. Users must configure at least one trusted location, typically their home or workplace, where the additional security measures won't be required. The setup process includes adding screen lock credentials, configuring biometric authentication, and optionally verifying a phone number for account recovery purposes.
Complementary Security Features
Alongside Identity Check, Google has expanded its security offerings with the AI-powered Theft Detection Lock, now available on devices running Android 10 or higher. This feature uses device sensors, Wi-Fi, and Bluetooth data to detect potential theft scenarios, adding another layer of protection to Android devices.
