Instructions

Want to prevent unauthorized users from modifying the BIOS or UEFI? Setting up an Admin Password creates a security barrier that prevents unauthorized users from changing the BIOS or UEFI settings without your permission. This guide walks you through the entire process, step by step.


What Is an Admin Password and Why Do You Need One?

Think of the Admin Password (sometimes called Setup Password) as a security lock for your computer's BIOS or UEFI settings. The admin password provides security by locking all the BIOS features and settings. The user can boot and see the BIOS settings, but they cannot modify them unless the correct admin password is provided to the computer.

Key Benefits of Admin Password Protection

  • BIOS Settings Protection: Prevents unauthorized changes to critical system settings
  • Hardware Configuration Security: Stops others from modifying boot order, security features, or hardware settings
  • Administrative Control: Allows viewing of BIOS but restricts modifications
  • Does NOT prevent normal booting: Your computer will start normally into Windows/operating system

Important: Admin vs System Password Difference

  • Admin Password: Protects BIOS settings modification (allows viewing, prevents changes)
  • System Password: Prevents computer from booting entirely (blocks startup completely)

Before You Begin: Important Things to Know

Password Requirements

  • Minimum length: At least 8 characters (if strong password is enabled)
  • Case requirements: Must include both uppercase and lowercase letters
  • Special characters: Latest models support special characters in the password

Warning: Store your password securely using a password manager. Forgot your Admin Password? Check out how to recover the Admin Password.
