Updating the Entra ID Login Configuration (after updating to 4Matrix Desktop 3.9.9.4 and beyond)

To support the latest Microsoft authentication requirements, the 4Matrix application now uses a secure localhost redirect URI for Microsoft Entra ID sign-in (applied in update 3.9.9.4, May 2026).

This section explains how to update your Microsoft Entra ID App Registration.

1. Open Microsoft Entra Admin Center

   • Open the following website: https://entra.microsoft.com
   • Sign in using an account with permission to manage App Registrations.

   

1. Open the 4Matrix App Registration

   • From the left-hand menu, select App registrations
   • Select the App registration used for 4Matrix

2. Open Authentication Settings

   • From the left-hand menu inside the App Registration:
     • Select Authentication
     • Select Redirect URI configuration
     • Find Mobile and desktop applications and choose Edit

   

3. Add the Localhost Redirect URI

   • Add the following Redirect URI: http://localhost
   • If a redirect URI currently exists similar to: https://login.microsoftonline.com/common/oauth2/nativeclient
     This can be removed
   • Save changes by pressing Configure

   

4. Test Login

   • Close and reopen the 4Matrix application. When signing in:
     • A web browser window will open
     • Microsoft sign-in will complete
     • The browser will redirect to a confirmation page
     • The 4Matrix application will automatically sign in

Why This Change Is Required

Microsoft no longer recommends the older https://login.microsoftonline.com/common/oauth2/nativeclient redirect method for desktop applications using the system web browser. The localhost redirect URI is now the recommended and more secure Microsoft authentication method.
