Passwords

You can set a power-on password, supervisor password, or system management password in UEFI BIOS to
prevent unauthorized access to your computer.
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.

Power-on password

A power-on password protects the system from being turned on by an unauthorized person. The password
must be entered before the operating system can be started. For instructions on how to remove the power-
on password, see "How to remove the power-on password" on page 28.

Supervisor password

The supervisor password protects the system information stored in UEFI BIOS. It provides the following
security features:
• If only a supervisor password is set, a password prompt is displayed when you try to enter the UEFI BIOS
menu. Unauthorized users cannot change most of the system configuration options in the UEFI BIOS
menu without the password.
