Preboot Authentication – using fingerprint instead of BIOS passwords

Different from Windows logon, authentication requests for BIOS passwords only work on the fingerprint
sensor when BIOS is configured to use. By default, BIOS recognizes the swipes on the fingerprint keyboard
if it is connected. If the fingerprint keyboard is not connected, BIOS recognizes the swipes on the internal
fingerprint device for authentication.

The BIOS setting Reader Priority can be changed to force the use of the internal fingerprint sensor, even
when the external fingerprint keyboard is connected. The default value for Reader Priority is External. The
setting can be changed to Internal Only to force the use of the internal fingerprint sensor.

Note: This BIOS setting applies to the fingerprint prompts on BIOS only. It does not have any effect on
Windows logon or Client Security Solution fingerprint authentication requests.

Configuring Fingerprint Software to enable preboot authentication

If you have set supervisor, power-on, or hard disk drive passwords in BIOS, you can configure the Fingerprint
Software for authentication instead of entering these passwords.
