BIOS/UEFI Master Password Generator

*Now updated to include later model laptops including new Dell 1FF6 & 6FF1 BIOS!!

Megabyte presents a quick & easy way to bypass BIOS passwords on (some, not all) laptops. \0/

HP, Compaq, Dell, Toshiba, Samsung, Sony, Acer, Asus, Fujitsu & more – your BIOS is brake. All your BIOS 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.)   bioslock

This one is for all who drink a little then play with their laptop security – they’ve seen this before.

Because while they were half-pissed they decide that upping their security level would be a good thing. And they’re not wrong, in itself, upping security levels is highly recommended. (I personally use an EFI lock combined with BitLocker drive encryption.) However, drinking & adjusting security levels are incompatible behaviours.

Being half-pissed, they’re bound to come up with a brand new & totes memorable password that – because it’s so brilliant – will not be remembered in the morning. *sigh*

Let me ask one of my favourite questions – What could possibly go wrong?

So, when you open your 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 @ 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. (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. With a bit of luck, you’ll be back on track in a few seconds.

If this worked for you, please take a few more seconds to leave a comment below, tell us about your win.

HP Probook/Elitebook owners – there is an alternative method available to you here in the Downloads section. Highly effective for the targeted machines, includes full instructions.

Asus laptop owners – yes, I’m talking to you. Asus, bless them, build an insecurity into your BIOS security *sigh*. There’s a fairly quick process to follow to find your particular BIOS/UEFI MASTER Password:

1. At the Password entry screen, press Alt+R – this will reveal a date code. Note the date.

2. If your date code is <2012, look up your corresponding password here.

3. Enter your BIOS/UEFI Master Password. Ka-ching!

4A. For those with date code >2011, EITHER temporarily transplant your hard drive into another computer, change the date in Windows to 31/12/2011, save & shut down. Return the drive to your Asus laptop & boot up again. At the BIOS/UEFI password prompt, enter AAOLDOA0 – which is the correct password for that date. Ka-ching!

4B. OR rather than remove the charger from your laptop, leave it connected but switch it off at the wall – now you have a solid earth connection. Remove the battery. Find your CMOS battery, carefully disconnect or remove that. Press & hold your power button (removes the last traces of current). Replace CMOS battery, replace main battery, turn charger on at the wall. Now when you restart, your internal clock will have defaulted to an earlier date.

5. Refer to step 2. Ka-ching!

  1. 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.

  2. 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

  3. 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.

  4. 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.

  5. 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
