Abstract
A system, apparatus, and methods are disclosed for aligning a stored scancode sequence that corresponds to a hardware password, with a password input device type such as a current keyboard type. Aligning the stored scancode sequence with the password input device type enables successful validation of a hardware password despite a change in a password input device type or inadvertent corruption of a non-volatile memory used for storing the scancode sequence such as non-volatile memory that stores BIOS information for a computing device.
