If your system has a supported fingerprint scanner, you can record your fingerprint and use it to log in. You must have administrative privileges to perform these steps.
First, record a fingerprint the system can use to identify you.
If your finger is too dry, you may have difficulty registering your fingerprint. If this happens, moisten your finger slightly, dry it with a clean, lint-free cloth, and retry.
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.
Now check that your new fingerprint login works. If you register a fingerprint, you still have the option to log in with your password.
Save any open work, and then logout. Select your name in the upper right-hand corner and then select "Log Out...".
A confirmation message will appear. Select "Log Out" to confirm. The login screen appears.
At the login screen, select your user name from the list. The password entry form will appear.
Within 30 seconds, select the fingerprint button above and to the right of your name.
The fingerprint button is labeled with a picture of a hand. If the timer runs out, the button will disappear and you will only be permitted to login with a password. If you want to try again, select the "Cancel" button and return to the previous step.
Swipe the finger you registered over your fingerprint scanner. You will be logged in.
If you previously created a login keyring, it is secured by your password. To unlock it, enter your password.
