    That's an openfirmware password - To forcefully remove that password you have to do two things:
    Add or remove DIMMs to change the total amount of RAM in the computer. Then reset the PRAM 3 times (Command + Option + P + R).

    DIMMs are your memory modules - sometimes just called RAM sticks. On a MBP you'll have to unscrew a plate from the bottom of the laptop to access them - but please research the proper way to remove one before attempting it. There are videos on youtube that you can watch to see how. You will likely have only 2 DIMMs installed so only remove one of them and then reset the PRAM before reinstalling the DIMM.
