Chapter 4. Secure your computer and information

Use the fingerprint reader (for selected models)

If your computer comes with a fingerprint reader, you can use it to enroll your fingerprints. After enrollment,
you can tap your finger on the fingerprint reader to log in to the system.
Enroll your fingerprints
Open the system menu and then click Settings ➙ Users ➙ Fingerprint Login. Then, follow the on-screen
instructions to finish the enrollment.
During the enrollment, the fingerprints are associated with the user password automatically. It is
recommended that you enroll more than one fingerprint in case of any injuries to your fingers.
Log in with your fingerprint
Maintain the fingerprint reader
To ensure that the fingerprint reader works correctly, do not:
• Scratch the surface of the reader with anything hard.
• Use or touch the reader with a wet, dirty, wrinkled, or injured finger.

Use passwords

This section introduces types of passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic
Input/Output System) and how to set, change, and remove a password.

Password types

You can set a power-on password, supervisor password, system management password, or hard disk
password in UEFI BIOS to prevent unauthorized access to your computer. However, you are not prompted to
enter any UEFI BIOS password when your computer resumes from sleep mode.
Power-on password
If you set a power-on password, a window is displayed on the screen when you turn on the computer. Enter
the correct password to use the computer.
Supervisor password
The supervisor password protects the system information stored in UEFI BIOS. When entering the UEFI
BIOS menu, enter the correct supervisor password in the window prompted. You also can press Enter to
skip the password prompt. However, you cannot change most of the system configuration options in UEFI
BIOS.
