    Question about recovering Asus bios password

    Hello, this is my first post on the forum, my apologies if i don't post in the right place.
    Im trying to recover an asus bios password using this method.
    I follow every step and it seems to work out well because i get a password but sadly the password doesn't work.
    In my case, there is 2 times the same string that perfectly match the decyption hex, so my guess was that there is an user & an admin password and they are the same.
    This is the string "0993C72677BA5C4DF3E012744407E89A0A2E8EC1E95444E89F7BFA0E55A2B0350BC9665CC1EF1C83".

    I would really like to understand what im doing wrong.
    I don't know if its relevant but the computer is an asus tuff FA506ICB-HN173 Motherboard DANJIMB18A0 Rev A

    ​post the complete bios
    and serial number of the machine to respect the forum rules.
    Have you tried cleaning the area?
    The password comes back?

      Alright my bad here it is:
      Serial Number: N9NRCX10B441398

      No i didn't try on this laptop, the full story is i bought 10 asus tuf laptops locked by bios password. My idea was to try to fix them to resell them.
      Anyway, on the first laptop i tried to recover the password with the same method and the password i got was not working, i then tried to blank the password in the bin file but that didn't work either as the pc was still asking for a password.

      I will try to clear that one also and see if it works this time.

          So i did try to clear the password myself, it didnt work the laptop was still asking for a password.
          Then i tried with your bin file and it worked!
          Thank you very much, do you mind me asking what did you blank exactly? I see in your bin file you did remove the password the same way i did, did you do anything else?

                i think is Raf040909 (for sure he has french layout keyboard). BTW, your xls decrypter file works great but sometimes it misses a special character, i.e. it missed "!" at the end of password.

                  decrypted passwords are for US layout keyboard, if you use external USB US keyboard it will work or try Raf040909 from your french layout laptop keyboard.

                      Well i won't try on this laptop because thanks to Maxpower there is no more password.
                      But i've just opened an other one and tried the same thing and it doesnt work aswell.
                      Ive tried Cqlvisqc & Calvisac, Ive tried to look up for differences other than A-Q on US-FR keyboard but nothing that would matter for this password. Not sure what else i can do. I don't have an US keyboard sadly.

                        If decode fails, delete password.

                            it means you have 2nd password, if you compare 1st bios you see it repeats 2 times, meaning bios pass and/or power on pass/hdd pass are the same.
                            2nd password is: calvisac (with small c)

                                  Found it!
                                  As i was going to clear it i was looking through the bin file and found an hex almost identical to the one posted above, the only difference is it start with 38 instead of 18 which gives a "c" instead of a "C".
                                  I then tried "calvisac" and it worked.
                                  Lesson learned for next time. Thank you guys for the help.

                                    Hello everyone,

                                    I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

                                    When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

                                    I decided to try flashing a new BIOS, but since I didn’t want to desolder...

                                    ASUS TUF A17 – BIOS password removal request
                                    by touftaf7301
                                    Hello everyone,

                                    I have an ASUS TUF A17 (model TUF707NV-HX088W, motherboard NJS / DA0NJSMBAF0 Rev F) that is locked by an UEFI BIOS password.

                                    I have already checked the BIOS guides, methods, resources and tools section but could not find a working method for this specific model.

                                    Details:
                                    – Make/Model: ASUS TUF A17 TUF707NV-HX088W
                                    – Motherboard: NJS / DA0NJSMBAF0 Rev F
                                    – Serial number: S7NRCX05W03829E
                                    – Issue: UEFI BIOS password locked (no access to BIOS setup or boot options)
                                    – BIOS dump attached below (read with RT809F)...

                                    ASUS TUF GAMING Z790-PLUS WIFI - BIOS Help
                                    by grimacelord
                                    Hello,

                                    I have spent the last hour on this and I guess this is just over my head, so here I am.

                                    I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.

                                    The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.

                                    Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...

                                    [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                                    by zenius
                                    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
