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.

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.

If you have set both the supervisor password and power-on password, you can use the supervisor password

to access your computer when you turn it on. The supervisor password overrides the power-on password.

System management password

The system management password can also protect the system information stored in UEFI BIOS like a

supervisor password, but it has lower authority by default. The system management password can be set

through the UEFI BIOS menu.

You can enable the system management password to have the same authority as the supervisor password

to control security related features. To customize the authority of the system management password through

the UEFI BIOS menu:

1. Enter the UEFI BIOS menu. See "Enter the UEFI BIOS menu" on page 25.
