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 NVMe
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 or through the think-lmi firmware-attributes sysfs class.
