Remove the BIOS password and reset the BIOS to its default settings if you have forgotten the BIOS password or bought a used computer without knowing its BIOS password: here are the methods you can use.

Have you ever forgotten the BIOS password set on your motherboard? Or bought a used computer planning to reinstall Windows, only to find you cannot access the BIOS because it asks for a password you know nothing about? In short, you now need to remove the BIOS password or reset the BIOS to its factory settings before you can access it or set a new BIOS password.

Cracking the BIOS Password

I currently have a Dell machine with a locked BIOS, and it shows a message like this: you only need to care about the code #2N4VVF2-6FF1

Then go to the website: https://bios.hoangngocquanganh.com

In the Enter Your Code field, enter the code your computer shows; mine is: #2N4VVF2-6FF, then click Find Password

Look at the line Dell from serial number:  GD5ZGStoMBbz6NBC (enter this code into the password box of the BIOS-locked machine; note that it is case-sensitive. * FOR SOME DELL CODES, PRESS CTRL-ENTER WHEN ENTERING THE CODE INTO THE BIOS )
