Using fingerprint authentication
If your keyboard has a fingerprint reader, you can use fingerprint authentication to replace passwords for
simple and secure user access. To use fingerprint authentication, first enroll your fingerprints and associate
them with your passwords (such as the power-on password, hard disk password, and Windows password).
Use the fingerprint reader and the fingerprint program to complete this procedure.
To use fingerprint authentication, do one of the following:
• For Windows 7: Open the Fingerprint Manager Pro or ThinkVantage Fingerprint Software program
provided by Lenovo. See “Accessing a program on the computer” on page 38. For more information
about using the program, refer to the help system of the program.
• For Windows 10: Click the Start button to open the Start menu, and then click Settings ➙ Accounts ➙
Sign-in options . Follow the instructions on the screen.
To use the fingerprint reader, refer to the documentation shipped with the fingerprint keyboard or located on
the Lenovo Support Web site at http://www.lenovo.com/support/keyboards.
