Biometric Playground is an open‑source demo app that helps developers and curious users explore Android's BiometricPrompt and Keystore‑backed public‑key authentication. Enroll a key with your device biometrics, validate with a secure challenge, inspect status logs, and clean up keys — all in one place. Highlights - Enroll: Create a device‑protected key pair (Android Keystore) gated by biometrics or device credentials. - Validate: Use BiometricPrompt to authenticate and sign a server‑provided challenge. - Delete keys: Remove previously enrolled keys from secure storage. - Configure endpoint: Point the app at your own demo API to test real challenge/response flows. - Inspect logs: See step‑by‑step status messages for each action. How it works - The app generates a hardware‑backed key pair (where available) and stores it in the Android Keystore. - When validating, the app prompts for biometrics and signs a challenge. If you configure a server endpoint, the public key and signatures are sent to that server for verification. - No raw biometric data ever leaves your device — only cryptographic material and metadata needed to perform verification. Privacy and data - No ads. No analytics. No tracking. - Biometric templates never leave the device; the OS handles them. - Keys live in the Android Keystore and can be deleted at any time from within the app. - If you use a custom server, only the public key and signed challenges are transmitted. Permissions - Uses the system BiometricPrompt. No special runtime permissions are required beyond enabling biometrics or device credentials on your device. Requirements - Android 8.1 (API 27) or higher recommended for BiometricPrompt. - A device with fingerprint, face, or device credential enabled. Open source This app is open source. Clone the repo to inspect the code, run tests, or adapt it to your needs.
