̽»¨´óÉñ

Windows uses Credential Providers to manage user authentication. When another authentication application is installed alongside the ̽»¨´óÉñ Agent (like Duo RDP or Microsoft Entra ID), ̽»¨´óÉñ's Credential Provider may become disabled. This article explains the symptoms and provides a resolution to ensure the ̽»¨´óÉñ Credential Provider functions correctly.

Symptoms

• The ̽»¨´óÉñ Credential Provider does not appear on the Windows login screen.
• Users are unable to authenticate via ̽»¨´óÉñ on Windows devices.
• Only the Duo Credential Provider is available for login.

Resolution

To resolve this issue, modify the Windows registry to enforce the ̽»¨´óÉñ Credential Provider:

1. Open the Windows Registry Editor (regedit.msc) as a Local Administrator.
2. Go to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Provider.
   
3. Check if the registry value forceJCCredProviderOnly (DWORD) exists. If it doesn't create it:
   1. Right-click on the Credential Providers key and select New > DWORD (32-bit) Value.
   2. Set the DWORD value depending on the desired outcome:
      • Set to 0: Allows both third party and ̽»¨´óÉñ credential providers.
      • Set to 1: Allows only ̽»¨´óÉñ Credential Provider.
4. Restart the device for the changes to take effect.
