Using the fingerprint reader
Depending on the model, your computer might have a fingerprint reader. Fingerprint authentication can
replace your passwords, such as the Windows password, power-on password, and hard disk password. In
this way, you can log in to your computer simply and securely.
Enrolling your fingerprints
To enable fingerprint authentication, enroll your fingerprints first. During the enrollment, the fingerprints are
associated with the Windows password automatically. It is recommended that you enroll more than one
fingerprint in case of any injuries to your fingers.
To enroll your fingerprints, do the following:
1. Open the Start menu and then click Settings ➙ Accounts ➙ Sign-in options .
2. Follow the instructions on the screen to finish the enrollment.
Scanning your finger
To scan your finger, tap the fingerprint reader with the top joint of your finger and hold your finger there for
one or two seconds with a little pressure. Then lift the finger to complete one scan.
