Log in to your computer securely
This section provides secure ways to log in to your computer with a password or your face.
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.
When a supervisor password is set, you are prompted to enter a valid password each time you try to enter
the BIOS menu.
If both the power-on password and supervisor password are set, you can enter either password.
However, you must use your supervisor password to change any configuration settings.
• Hard disk password
