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

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

 

The BIOS (Basic Input/Output System) password is a security feature designed to prevent unauthorized access when the computer is booting. The BIOS 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 BIOS password, and only after entering the correct password can the user access and modify BIOS 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: BIOS is firmware that runs when the device starts, responsible for initializing hardware and booting the operating system.

 

You can set four types of passwords in the BIOS:

  • Administrator Password: If only the administrator password is set, access is limited to the setup program (BIOS or UEFI). You must enter the administrator password to access and change BIOS 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 BIOS. In the BIOS settings, the user will have administrator rights.
    Note: If both the administrator password and user password are set, when entering the BIOS settings, you must enter the administrator password to access and change BIOS settings. If the user password is entered, you can only browse but not change BIOS settings.
  • HDD Password: If an HDD password is set, when booting the device or entering the BIOS 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.
  • OPAL Password: OPAL is an encryption standard for storage security established by the TCG (Trusted Computing Group) for hard drives and SSDs. If an OPAL password is configured, the system will prompt for the 「TCG Storage Security Driver Password」 upon startup or when entering the BIOS. Only with the correct password will the drive be unlocked, allowing the device to boot normally or access the data stored on the drive.
    Note: The OPAL password feature is available only on select models.
