UEFI BIOS passwords
You can set passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/Output System) to
strengthen the security of your computer.
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
When a power-on password is set, you are prompted to enter a valid password each time the computer is
turned on.
• 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.

the BIOS menu.
If both the power-on password and supervisor password are set, you can enter either password.

disk password is set, you are prompted to enter a valid password each time you try to access the storage
drive.
Note: After you set a hard disk password, your data on the storage drive is protected even if the storage
drive is removed from one computer and installed in another.
• System management password (for selected models)

password to control security related features. To customize the authority of the system management
password through the UEFI BIOS menu:
