Free library for resetting windows password?

6 posts in this topic

Recently, I am interested to build a windows app to reset Windows login password as a side off project. I am still a newbie in programming so i am not able to build the app from scratch. Is there any open source  project i could learn from on this?

Hi, @clariceo0, welcome to the forum. A couple of questions to help us help you:

  • Are you looking to change the password from within the machine itself or remotely?
  • Are you doing this on domain computers, or just local users on local PCs?
  • Are you wanting to allow users to do this themselves (something sitting on the desktop they can click on), and if so do they have administrative rights to do so?

The more info you can provide us with, the better we can assist you, so we're not throwing out suggestions that may not work for your situation.

 thanks for the great suggestion. I just want to change or reset the password of local account. I will write a GUI client for this to help normal users without much technical knowledge.

@clariceo0 Usually we follow more of a "teach a man to fish" motto rather than just handing folks scripts, but I had this one lying about. It should give you an idea how to proceed anyway; you will probably need to modify to your needs. Also you'll want to test heavily; it is an older script which I have not tested on Windows 10. Let me know if you have any questions:

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>

Local $sUserName, $sPassword

$hGUI = GUICreate("Reset Local Password", 300, 300)
    GUISetState(@SW_SHOW)
    GUISetFont(11, 400, Default, "Arial")

    $lblUserName = GUICtrlCreateLabel("Username", 115, 10, 65, 30)
    $lblPassword = GUICtrlCreateLabel("Choose New Password", 75, 90, 150, 30)
    $lblVerify = GUICtrlCreateLabel("Verify New Password", 75, 170, 150, 30)

    $inpUserName = GUICtrlCreateInput(@UserName, 10, 40, 280, 30, $ES_CENTER)
    $inpPassword = GUICtrlCreateInput("", 10, 120, 280, 30, $ES_PASSWORD)
    $inpVerify = GUICtrlCreateInput("", 10, 200, 280, 30, $ES_PASSWORD)

    $btnGo = GUICtrlCreateButton("Change Password", 10, 250, 125, 35)
    $btnClose = GUICtrlCreateButton("Exit", 165, 250, 125, 35)

    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE, $btnClose
                ExitLoop
            Case $btnGo
                If GUICtrlRead($inpPassword) == GUICtrlRead($inpVerify) Then
                    $sUserName = GUICtrlRead($inpUserName)
                    $sPassword = GUICtrlRead($inpPassword)
                    _changePW($sUserName, $sPassword)
                Else
                    MsgBox(0, "Reset Local Password", "Passwords do not match!")
                EndIf
        EndSwitch
    WEnd

Func _changePW($UserName, $Password)
    $oUser = ObjGet("WinNT://" & @ComputerName & "/" & $UserName)
        If IsObj($oUser) Then
            $oUser.SetPassword($Password)
            $oUser.SetInfo
        EndIf
EndFunc

 

   Edit: Also, although you posted in a C++ forum you didn't specify that you need this done in C++/C. Are you just looking to get the job done, or do you have a language requirement that it needs to be coded in?

@JLogan3o13 thanks for the help. I will figure out the code myself and port it into C++.  so i can build a GUI with QT.  I find a good example of the program called UUkeys. Here is the tutorial on how to reset windows password. that is exactly what i am looking for.

You can use the api fuction NetUserChangePassword.

#ifndef UNICODE
#define UNICODE
#endif
#pragma comment(lib, "netapi32.lib")

#include <stdio.h>
#include <windows.h> 
#include <lm.h>

int wmain(int argc, wchar_t *argv[])
{
   DWORD dwError = 0;
   NET_API_STATUS nStatus;
   //
   // All parameters are required.
   //
   if (argc != 5)
   {
      fwprintf(stderr, L"Usage: %s \\\\ServerName UserName OldPassword NewPassword\n", argv[0]);
      exit(1);
   }
   //
   // Call the NetUserChangePassword function.
   //
   nStatus = NetUserChangePassword(argv[1], argv[2], argv[3], argv[4]);
   //
   // If the call succeeds, inform the user.
   //
   if (nStatus == NERR_Success)
      fwprintf(stderr, L"User password has been changed successfully\n");
   //
   // Otherwise, print the system error.
   //
   else
      fprintf(stderr, "A system error has occurred: %d\n", nStatus);

   return 0;
}

      I'm a command-line kind of guy, and I write scripts primarily for myself.  Since many websites nowadays require strong passwords, I thought I'd write a simple password generator in AutoIt. I know that AutoIt mavens have written more elaborate pw generators; I offer mine for what it's worth. The compiled script, GenPass.exe, can be downloaded here. See below for Help text and source. Enjoy!
      Updates:
      2017-05-06: Default password changed to variable length of 13-22 characters; argument "1" no longer supported
                            When compiled as GenPW.exe, password is sent directly to the clipboard, no message box unless password generation fails.
      2017-05-05: Correction to bypass password generation if argument is ?|H|h
      2017-05-03: Added special argument 1 to generate a password of variable length (10-18 characters) including two (2) separator characters
      2017-05-02: Added option /S to set a (persistent) randomization seed
      Help:
      GenPass.exe|GenPW.exe -- CLD rev. 2017-05-06
      Generate a strong password and save it to the Windows clipboard
      Note: GenPW.exe has the same functionality as GenPass.exe, but
            sends the generated password directly to the clipboard.
            No message box is displayed (unless password generation fails).
        
      "Strong" means that the password contains random combinations of
      alphnumeric characters, including at least one uppercase letter
      (A-N,P-Z), one lowercase letter (a-k,m-z), and one number (0-9).
      (Generated passwords do not use uppercase O or lowercase l as
      these characters are easily confused with the numbers 0 and 1.)
      The length of the password is up to you (see Usage, below),
      but needless to say, the longer, the stronger.
      By default, GenPass generates a strong password of between 13
      and 22 characters that includes two of the following separator
      characters: $%&()*+,-./:;@[]_. Alternatively, you can supply a
      command-line argument in which any number n from 1 to 9 stands
      for a random sequence of alphanumeric characters of length
      n, and any other character stands for itself. Thus, you can
      include fixed words and other characters, such as separators,
      in the generated password. Spaces in the argument are converted
      to underscores. Here are some examples:
      Usage             Sample output
      -----             -------------
      GenPass           MqU26A*6dS-53r8
      GenPass 9         frdhPYDs9
      GenPass 58        weoXYHKxDI1uQ
      GenPass 5.5       UfA6j.43VBB
      GenPass 3-4-3     0I0-6gq4-njc
      GenPass 5,3.7     I2FSR,tRZ.fjeIsFy
      GenPass 3)5(3     UMf)m8513(CBq
      GenPass 3[haha]3  yLa[haha]P3y
      GenPass Yes way5  Yes_way1BsUh
      Seed Option (/S)
      ----------------
      Adding switch /S to the command-line argument causes GenPass to
      set a seed for the random generation of password characters. A
      bare /S sets a randomized seed which is written to disk in a file
      named GenPass.rnd; this seed is used for all subsequent launches
      of GenPass with the bare /S option. Alternatively, you can specify
      a seed (range -2^31 to 2^31-1) on the command line with /S [seed].
      Here are some examples:
      GenPass /S
      GenPass /S 33.3333
      GenPass 5,5,5 /S
      GenPass 5,5,5 /S 33.3333
      Note that any subsequent launch of GenPass without the /S option
      will cause GenPass.rnd to be deleted.

      Hi guys,
      I have a pretty advanced question...
       
      This is the issue i'm facing :
      On a regular basis we need to install pfx certificates (with password protection) on devices from external companies.
      To install the certificate we always have to contact the user, setup a really dull and long process to get an RDP session to that device, install the certificate.
       
      I'm looking for :
      a way to generate exe files on the fly, that will include the pfx file and password, and automatically install them without any interaction from the user, and the user not being able to retrieve the password to install the certificate.
       
      Question :
      Is this possible with AutoIT? And if so, does anyone have a working example for the certificate installation part or the auto generate with file include?
       
      Thx in advance

      Hello,
      I have compiled a reference DLL in VS 2015 Community and this  DLL works fine with project for which it is used. There is an interface from which u can access functions in DLL.
      Developers stated that this DLL is almost universal and can be used with any language with minor changes.
      I am trying to access its function from Autoit script and got an error 3, after calling DLLCall - "function" not found in the DLL file.
      Please have a quick look, I feel I miss something in C++ library with exporting functions and I do not know what to add as I am new to C++.
      Thank you.
      Source files and script also attached.
       
      Here is my script.
      Local $dll = DllOpen("C:\Users\Home\Desktop\dll\user.dll") ConsoleWrite("$dll handle = " & $dll & @CRLF) ;$dll handle = 1 Local $result = DllCall($dll, "double:cdecl", "ProcessQuery", "str", "dll$mynumber") If @error > 0 Then ConsoleWrite("Error: " & @error & @CRLF) ;Error = 3 If IsArray($result) Then ConsoleWrite("Array returned!" & @CRLF & "dll$mynumber: " & result[1]) Else ConsoleWrite("$result is not array. : " & $result & @CRLF) ;$result = 0 EndIf DllClose($dll) And here is dll source. As I understand, function "ProcessQuery" exported with help of DLL_IMPLEMENTS

      With _WinWaitActivate we can wait for a window to process it.
      But is there any logic so that we can wait for this window title and based on the window text (like 2 or more patterns will be there) we can click yes or no on the window.
