About BIOSPassmaster

BIOSPassmaster.com provides laptop BIOS Master Passwords that successfully unlock BIOS locked laptops by all the major PC manufacturers – Dell, HP, Acer, Asus, Lenovo, Alienware, Fujitsu, Samsung & more. We also unlock Bitlocker-encrypted hard drives too.

In general, when you enter a wrong password into a BIOS-locked laptop, the laptop will respond with a message like “This laptop ABCD1234 is locked. Enter password to continue”. The ABCD1234 ID is the Challenge Code, an encoded representation of the BIOS Master Password required to gain entry. Our skill is in deciphering that Challenge Code so that you can use your laptop.
