Google has launched a new feature, Restore Credentials, as part of Android’s Credential Manager API to simplify account access restoration for third-party apps when users switch devices. This automatic, background process allows users to log in seamlessly using encrypted restore keys, enhancing security and user experience during transitions.
**Meeting Takeaways: Nov 25, 2024 – Mobile Security / Privacy**
1. **New Feature Introduction**: Google has launched a feature named “Restore Credentials” within its Android Credential Manager API. This feature allows users to seamlessly restore account access to third-party apps when migrating to a new Android device, eliminating the need to re-enter login credentials for each app.
2. **Automatic Sign-in Process**: The restoration process occurs automatically in the background when users restore their apps and data from a previous device. This enables users to sign back into apps without additional interaction.
3. **Technology Utilized**: The feature uses a restore key (a public key compliant with FIDO2 standards) that is saved locally in an encrypted format on the device’s Credential Manager. Users have the option to store this encrypted key in the cloud if they have cloud backup enabled.
4. **Developer Guidance**:
– Developers can generate a restore key after user authentication.
– It’s advised that developers delete the restore key once the user signs out to prevent automatic log-ins.
5. **Comparison with Apple’s Feature**: Apple has a similar capability in iOS, using a specific security attribute (kSecAttrAccessible) that manages app access to credentials stored in iCloud Keychain, including conditions for device restoration.
6. **Additional Updates**: The meeting also covered Google’s release of the first Developer Preview of Android 16, which includes updates to the Privacy Sandbox and an enhanced Privacy Dashboard. The dashboard will now show which apps have accessed sensitive permissions in the past week.
7. **Updated Security Paper**: Google has released an updated Android Security Paper detailing built-in security features like theft protection, private space, sanitizers, and a lockdown mode aimed at securing device access.
8. **Next Steps/Follow-Up**: Participants are encouraged to follow further developments on Google’s features and security updates through their official social media channels.
**Note**: Keep an eye on the implementation of these features and how they compare to existing solutions from competitors.
