Finger Scanner

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.

Register a Fingerprint

You can register up to three fingerprints. A 
password is also set up as an alternative to your 
fingerprint.

1.  From a Home screen, tap 

 Apps > 

 Settings > Device.

2.  Tap Finger Scanner > Fingerprint manager.

3.  Swipe your finger over the Home key to register 

your first fingerprint or to continue to the next 
screen.

Change Backup Password

To change the backup password:

Fingerprint Verification

accounts accessed from your device.
