Pass a password to runas with command RunAsSpc

RunAsSpc can be used like the runas command, but additionally with a password parameter.

RunAsSpc.exe /program:"path\yourApp.exe" /user:"anyAccount" /password:"accountPassword"
As example:
RunAsSpc.exe /program:"c:\windows\system32\regedt32.exe" /user:"admin" /password:"pw"
RunAsSpc command line call
There is no security check and the password is in clear text.

If you want to hide the login credentials you can configure an encrypted file

either by RunAsSpc.exe on command line or by the graphical user interface RunAsSpcAdmin.exe.
Take a look below on >> Build encrypted files <<.

Then you can call this encrypted file with RunAsSpc.exe as follows:

  1. If the name of the encrypted file is >> crypt.spc << , you can start it by a double-click on the same directory.
  2. Drag your encrypted file and drop it onto RunAsSpc.exe
  3. On command line >>RunAsSpc.exe /cryptfile:"path\NameOfCryptfile" <<
  4. Create a shortcut or link like >> c:\path\runasspc.exe /cryptfile:"path\NameOfCryptfile" <<
  5. Link the file extension (open with) *.spc on your system to RunAsSpc.exe, to run the encrypted file by double-click.
  6. You can also use your own file extension.
