Use passwords

Password types

You can set the following passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/

Output System) 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

When a power-on password is set, you are prompted to enter a valid password each time the computer is

turned on. The computer cannot be used until the valid password is entered.

• Supervisor password

Setting a supervisor password deters unauthorized users from changing configuration settings. If you are

responsible for maintaining the configuration settings of several computers, you might want to set a

supervisor password.
