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.
When a supervisor password is set, you are prompted to enter a valid password each time you try to enter
the BIOS menu.
