Laptop BIOS Master Password Generator

If you need your Laptop BIOS Password Reset, then you’ve come to the right place. The Laptop BIOS Master Password Generator reveals the password for many popular laptops. Not all laptops are vulnerable but many are – give it a try, it’s free.

Achieve Laptop BIOS Password Reset on HP, Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo & Fujitsu & more brand name laptops with the Laptop BIOS Master Password Generator!

Those manufacturers listed above – your BIOS is brake. All your password are belong to us. (Well, nearly all.)

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)

And what?




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 @

Many HP/Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo or Fujitsu laptop BIOS passwords can be revealed.

Hints & Tips

In the case of Asus laptops it’s the date code you require – enter an incorrect password then press Alt +R at the next prompt. Take that date & enter it in the BIOS Master Password Generator below in the same order (yyyy-dd-mm or dd-mm-yyyy) as displayed on your Asus laptop.
If your laptop has an Insyde H20 BIOS, then your secret sauce is to use a USB keyboard to enter the master password generated here.
HP EliteBook/ProBook
For Elitebook & ProBook (up to 2014) there is an alternative method available here in the downloads section. Highly effective on vulnerable machines, full instructions included.
Late Model HP
Envy, Omen, Spectre, ZBook, Elite, Pro, Folio & more can access our premier guaranteed solution. Confirmed working 100% on all current HP laptops except X360 & X2.
After entering the password in Dell laptops, press & hold the left Ctrl key then hit Enter twice.  Some Dell service tags are missing a suffix – first try the password generated, then try the passwords for all suffices by adding either -595B, -2A7B, -D35B, -1F66 or -6FF1 to your service tag. Downgrading your BIOS can change your suffix, resulting in a successful password generation.
For the later 6×4 password implementation, download & install Python 2.7 (available for all platforms), then grab the Fujitsu 6×4 Python script & save it in your Python directory. Double-click on the script, follow the simple instructions,  all done.
If your response code pattern is 4 x 4, then it’s a one-time password, generated fresh each boot. Do not turn the laptop off after obtaining the Challenge Code as the Master Password is specific to that code. Restarting before the password is entered will require a new Master Password.
List of Vulnerable BIOS
Compaq 5 decimal digits, 10 characters Dell bios code ending with -595B, -D35B, -2A7B, -1D3B, -1F66 & -6FF1, also with no suffix. Fujitsu-Siemens 5 decimal digits, 8 hexadecimal digits, 5×4 hexadecimal digits, 5×4 decimal digits Hewlett-Packard 5 decimal digits, 10 characters Insyde H20 8 decimal digits Phoenix 5 decimal digits Sony 7 digit serial number, 4 x 4 one-time Samsung 12 hexadecimal digits Asus Date code

Anyway, whichever BIOS-locked laptop you have, grab the Machine ID Code - sometimes called the Service Tag, Challenge Code or Response Code  - usually displayed after submitting a few (3-5) incorrect codes - that’s the unique identifier we need. Pay special attention when reading the code, be careful not to confuse I & l or O & 0, B & 8, S & 5.

Now enter that code in the box below, hit the Crack It button.... Ka-ching!! No surveys to fill out, no pop-under pR0n adverts, just pure goodness & quite likely your Laptop BIOS Master Password too.

  1. Just to share the love, eventually got working on a Dell e5470 but for whatever reason I needed a separate USB keyboard. Do this and check and recheck your O versus your 0, your l versus your I etc. THIS DOES WORK.

    1. Yup, that’s what you gotta do on some (not all) Dell laptops. All visitors should read the provided information before using te generator, doing that seriously improves your chance of success.

  7. Hey Rene,
