The password setting is needed especially when there’s confidential or private data on a computer. Today, I’m going to tell you how to set the BIOS or UEFI password on Windows step by step.

What Is BIOS or UEFI Password

As everyone knows, a password helps a lot to prevent people from accessing your device without your permission. This is a good way to control access and protect privacy. By setting a BIOS or UEFI password, you can:

  • Prevent people from logging into the certain operating system.
  • Prevent booting from any removable devices.
  • Prevent others from changing BIOS or UEFI settings.
  • Prevent others from installing another operating system.

Yet, the access to other systems is still available.

FYI: what if you run into operating system not found error?

BIOS or UEFI Password vs. Login or Account Password

Some people may ask what the difference is between the BIOS or UEFI password and the login or account password since both of them are used to prevent malicious access and protect data.

  • Indeed, though the login password or account password is built in the Windows to help ensure data security, it can be easily bypassed by using third-party tools. What’s worse, in some cases, even the third-party tool is not necessary.
  • Well, the BIOS or UEFI password is lower-level password, which can’t be bypassed by people. So you can enjoy high data security through BIOS or UEFI password setting.
Tip: The biggest problem may be: unlike Microsoft account, there is no recovery option for BIOS or UEFI password. But don’t worry, you can recover or reset a BIOS or UEFI password for Windows computers.
