Finger Scanner, Register a Fingerprint, Change Backup Password

Use fingerprint recognition as an alternative to entering passwords in certain apps.

You can also use your fingerprint to verify your identity when logging in to your Samsung account.

Note: Fingerprint recognition uses the unique characteristics of each fingerprint to enhance the security of your device. The likelihood of the fingerprint sensor confusing even small areas of two different fingerprints is very low. But in rare cases, the sensor may recognize a fingerprint that is similar to a registered fingerprint.
