If your system has a fingerprint scanner, you can record your fingerprint and use it to log in. You must have administrative privileges to perform these steps.
Select your user name in the upper right-hand corner, then choose "My Account".
Unlock your account using the "Unlock" button at the bottom left of the User Accounts tool.
Enter your password at the prompt.
Select the "Disabled" option next to "Fingerprint Login".
Select an option for the fingerprint you want to register. You may choose your right index finger, your left index finger, or a different finger. Then select "Forward".
Swipe the finger you selected three times at moderate speed over your fingerprint reader. Each time the fingerprint reader recognizes your fingerprint properly, the corresponding picture of a hand will transform into a picture of a fingerprint with a check mark. After the third swipe, you will see the message "Done!"
Select "Forward". You will see a confirmation message that your fingerprint was saved successfully. Select "Close" to finish.
If you register a fingerprint, you still have the option to log in with your password.
