Biometric authentication
Also called: Biometrics, Face ID, Touch ID, Fingerprint login
Unlocking a saved login with Face ID, Touch ID or a fingerprint.
Definition
Biometrics don't replace the password on the server; they unlock credentials stored securely on the device. Testers check enrollment, failed scans, fallback to passcode, and what happens when the user adds a new fingerprint.
In practice
After three failed Face ID scans, the banking app should offer the app PIN instead of locking the user out.
