UltraVNC Password Decrypt Online: A Simple Guide

If you’re looking for a way to decrypt your UltraVNC password, you’re in the right place. Although Windows provides a remote desktop feature that does something similar, UltraVNC remains popular for its cross-platform compatibility and free use (unless you’re using premium versions of RealVNC for extra features like the deployment tool).

UltraVNC stores its encrypted password in an INI file, and there are methods to easily decrypt it online.

Locating the encrypted VNC password

Unlike most VNC software that stores encrypted passwords in the registry, UltraVNC saves it in an INI file. Here’s how you can locate the encrypted password:

1. Navigate to the C:\Program Files\UltraVNC folder.
2. Open the ultravnc.ini file.
3. Look for passwd or passwd2. These values represent the encrypted password.

If you’re looking for passwords for other VNC variants, here are the locations:

• RealVNC
  HKEY_LOCAL_MACHINE\SOFTWARE\RealVNC\vncserver
  Value: Password
• TightVNC
  HKEY_CURRENT_USER\Software\TightVNC\Server
  Value: Password or PasswordViewOnly
• TigerVNC
  HKEY_LOCAL_USER\Software\TigerVNC\WinVNC4
  Value: Password
• UltraVNC
  C:\Program Files\UltraVNC\ultravnc.ini
  Value: passwd or passwd2

Once you’ve located the encrypted VNC password, you can proceed with decrypting it using one of the following methods.
