BIOS Master Password

Laptop BIOS Master Password Generator

Bypass laptop BIOS passwords on Dell, Sony, Asus, Acer, Samsung, Fujitsu, Toshiba, HP, Compaq & more brand name laptops with the BIOS Master Password Generator! \0/

Updated April 2018, now includes Asus date codes & Dell 1F66/6FF1 codes!
(as mentioned here)

Those manufacturers listed above – your BIOS is brake. All your password are belong to us.

8-digit BIOS provided by Insyde H20 and 5-digit Phoenix BIOS are also pwnd.

Seen this before? Bios-locked & password lost, that’s what that screen indicates.  But the 20-digit machine ID code displayed can often be decrypted to reveal the BIOS password. (That code reveals a Fujitsu-Siemens laptop with password 9538393.)

BIOS Master Password

 

When you open a laptop & find yourself faced with the immediate black BIOS password screen & absolutely no idea of what password you used, all you gotta do is come to this page @ 1024kb.co.nz. Most HP, Compaq, Dell, Toshiba, Samsung, Sony, Acer, Asus or Fujitsu laptop BIOS passwords can be revealed.

Anyway, grab the Machine ID Code – sometimes called the Service Tag – usually displayed after submitting a few (3-5) incorrect codes.

In the case of Asus laptops it’s the date code you require – press Alt +R at the password prompt. Take that date & enter it in the BIOS Master Password Generator below.

On some HP/Dell machines, you may need to press Right Ctrl+Enter to show the ID code – & Left Ctrl+Enter to submit the password.

Now enter that code in the box below. When you’ve got your master password, please leave a comment, tell us about your win…

HP Elite / ProBook owners there is an alternative method available for you here in the downloads section. Highly effective on vulnerable machines, full instructions included.

  1. Acer Aspire R3-131T-C1YF
    S/N NXG10AA005541017626600
    F2 Forgotten Password
    3 times gives gets me to Bios however can’t clear Supervisor Password

    Tried Multiple software with no luck

    MUST fix for school use

    1. Have you got the BIOS key hint? If not, Acer BIOS clears when you remove the CMOS battery, main battery, power connection & RAM, then press the power button for 15 seconds to clear any last residual bits of current. Now replace everything & you’re good to go.

  2. If you’ve got a BIOS lock, I would use the longer Dell from Serial password. If it’s merely a HDD password – you’ll know this for sure if you swap the HDD & boot successfully – then use the shorter password.

    Don’t forget to hold the right Ctrl key when you press Enter to validate the password.

    1. Well, that’s where I’m stuck….I have 3 HDD’s but they’re junk they don’t work. So worse case scenario is that I have to go and buy a new HDD. I think that’ll cure the problem! Thanks for your time Megabyte.

      1. Try booting without a hard drive, see if you get dropped into the BIOS/UEFI. You won’t do any damage. If so, it’s a HDD lock for sure & you’ve just been given the password.

        If you’re running Win10 on another laptop, that drive will just slot in & highly likely boot straight up. The other option is to download a Win10 PE .iso, use Rufus to burn it to USB & boot from that.

        (It’s not really burning, there’s no smoke)

        1. Alright, I’ll try that but the only other laptop I have belonged to my late uncle and I’m not comfortable opening it up it works and I don’t want to mess it up. I’ll let you know what I come up with going without the HDD.

    2. Ok, it definitely has a system or bios pw. But I found the only sn in the batt comp and input it into the generator and it doesn’t pop up any codes. My sn is CN-OU692R-12961-973-3277-AO1 not sure if the O’s are zeros or vice versa? It’s got windows vista as the current OS so it looks like a lost cause. Thank you for your efforts I’ll be back I want to see the generator work successfully seeing others having good luck it has to be for real. Take care

        1. Heck ya that worked but there is a HDD pw and the one the generator gave me didn’t work but I’ll keep at it thank you so much.

          1. If it’s not the original hard drive, maybe it’s one locked by another machine, then no, the generated password won’t accept. Maybe the original drive is one of the other drives you have? Try them if you think that’s possible. Hard drives will only unlock in the laptop with which they were originally locked.

            If not, a new HDD isn’t a major expense, but for a 10-year old laptop I’m sure you can pick up a reasonably reliable used drive at your local recycling center. Scavenge 2x 2GB DDR2 RAM – that’s your biggest performance booster. Then install Ubuntu or another lightweight OS on it & you’ve done a good thing, returning old junk to life, making it useful for someone instead of useless to everyone.

            1. Honestly speaking I’m not a big fan of Ubuntu but I guess in this case I have no other choice right? It’s actually my cousins laptop given to her by her friend who passed away and that’s the reason for the password dilemma. Anyways I am a believer in your generator it worked awesomely. Now if I can get past iOS heh heh, I’d be in trouble. Lol have a good night and once again thank you a million.

  3. Does your code generator work for Dell Latitude E6400 96ZYRK1-2A7B is the service tag number on the system/admin password entry white screen. Or would that be a HDD password? Thanks, James

  4. please please help ,
    i have a proof of purchase of laptop fujitsu lifebook AH531
    I forgot my bios password ,I can’t boot can you please help ?

    1. Richard, Vaio VGN uses the notorious 4×4 pattern one-time BIOS code where the 4×4 code changes each reboot – hence the one-time reference.
      Go ahead, grab the 16 digits showing on your errant laptop screen & enter them into the BIOS Master Password Generator. Click the Crack It button & you’ll have your answer.
      If you are doing this remotely, make sure the Vaio doesn’t shut down between you taking the 4×4 code & entering the master password.

  5. i have a samsung laptop my code is an 18 diget one:50E0B09B6E77BD9C231 but “dogbert”‘s
    only goes to a 12 didget code what do i do in this situation?

  6. Yes! It worked! God, I have been trying to solve this problem for days. I have a Dell Latitude E7440. My code ended in 6FF1 and I used the ‘Dell from serial number’ password that this page generated. I entered the password and then pressed left-control and enter. BINGO!

  7. my codes will not work it’s tag 7YWKNJ2-6FF1 I’m pushing crtl+enter but no luck can you help me out

  8. I Cant get the button to respond after i enter my service tag. its a dell latitude e6440 service tag 8x6td12 and the machine id is 238QSK1K2AA-1F66. CAN YOU PLEASE HELP ME?

    1. Hi Steve, bugger, I was doing some updating on that page this morning, must have forked something up. I just tried it with Chrome on my iPad though, here’s your code – S8EME9kKDUMUVqof

  9. You are the best for a dell 6FF1 I have entered the “Dell from serial number” field password and pressed left CTRL and ENTER (not the OK button)

    P.S. the Service Key that you enter is case sensitive !!!

    Where can we donate?

    TKS

  10. I just ran a Dell 6FF1 UEFI successfully, B02HMC2-6FF1 was the Asset Code, master password response generated fz0Ibn3vHw321fNs – which is correct.

    Two points to consider: the 4th character is an upper case i – not lower l, & even if you have entered the password correctly, you still need to hold the right-side Ctrl key when you press Enter.

    1. Hi John, it’s not so much the laptop manufacturer that’s relevant here, it’s the bios provider who is targeted.

      Award bios is used by several laptop manufacturers, for example. Award own Phoenix, there’s also Insyde & AMI brand bios too. Very rarely do the manufacturers write their own custom bios. Even if the bios is self-branded, there’s a high likelihood of simple rebranding going on.

      If your (insert brand name here) laptop has a bios that reports back with a challenge code – This Laptop XYZ123456 Is Locked – or similar, then you know that the possibility of decoding the password exists.

      I don’t have a Toshiba laptop & I’m not certain who makes the bios in those models you mention.

      My best suggestion is to give it a go, it’s free to use & I’d be interested to know the answer too.

      Cheers, thanks for stopping by @1024kb.co.nz

  11. I’ve updated the decrypting JavaScript to include later model laptops today. It’s still a case of “some, not all” but this solution does cover the majority of brand name laptop manufacturers – Dell, HP, Sony, Acer, Samsung etc, and now includes their late model products too.

  12. Is not working. Button not even respond. Stupid button… Okay I make joke, that was joke. Is a nice button.

    Can you help with fix or workaround? Maybe I do something wrong, but still I get no error code.

    I enter my challenge code: AL2MY-N48VX-2TD8G-JH4UH-KCG5K

    1. What brand of laptop is giving you that response code?

      As it says up the top of the page – for some, not all laptops. Maybe (sadly) this is not one that the decryptor works on.

  13. So like my boyfriend says “no, that laptop is f**ked” and I think “I’m gonna go ask Megabyte” and I don’t even ask, I just use this page. I put the code numbers and letters in then click Decrypt and Yis! it worked!! And all my friends are going “Yis, girl power!” and now I am a l33t haXX0r!
