How to Configure or Resolve Forgotten Bioses Password/UEFI Password/Boot Password

Applicable Products: Notebook, Desktop, All-in-One PC, Gaming Handheld, Motherboard, MiniPC

 

The Bioses (Basic Input/Output System) password is a security feature designed to prevent unauthorized access when the computer is booting. The Bioses password is also known as the system setup password, UEFI password, boot password, or security password.

When the device starts, it prompts the user to enter the Bioses password, and only after entering the correct password can the user access and modify Bioses settings and enter the operating system. This provides an additional layer of security to prevent unauthorized individuals from altering hardware configurations or the boot process.

Note: Bioses is firmware that runs when the device starts, responsible for initializing hardware and booting the operating system.

 

You can set three types of passwords in the Bioses:

  • Administrator Password: If only the administrator password is set, access is limited to the setup program (Bioses or UEFI). You must enter the administrator password to access and change Bioses settings.
  • User Password: If only the user password is set, this serves as the boot password, and you need to enter this password when booting into Windows or entering the Bioses. In the Bioses settings, the user will have administrator rights.  
    Note: If both the administrator password and user password are set, when entering the Bioses settings, you must enter the administrator password to access and change Bioses settings. If the user password is entered, you can only browse but not change Bioses settings.
  • HDD Password: If an HDD password is set, when booting the device or entering the Bioses settings, the system will prompt for the HDD password. Only after entering the correct password will the hard drive unlock, allowing the device to boot normally or access data stored on the hard drive.  
    Note: Only some models are configured with HDD password settings.
