Biometrics
To improve your security, features that use biometrics (face, fingerprints, and irises) are only available when you use a secure screen lock type (pattern, PIN, or password). When you switch to a non-secure screen lock type (Swipe or None), biometric authentication is suspended for unlocking and for verification in apps like Samsung Pay and Samsung Pass. If you’re using biometrics now without a secure screen lock type, you’ll be able to continue after the upgrade, but changing to a secure screen lock type is recommended.Quick Panel
