Discovering Core Partner System Functions

Resolving Digital Hub Access Difficulties

⚠️ Unable to Log In

Cause: Incorrect credentials, authenticator issues, or forgotten password.

Solution: We know being locked out is stressful. First, double-check your username and password for typos. If you suspect you've forgotten your password, use the 'Reset Password' link on the login page. Ensure your Windows app and authenticator are correctly installed and updated, and that you are using the correct codes as required since January 18, 2026. For persistent issues, contact your dedicated partner manager.

⚠️ Windows App or Authenticator Problems

Cause: Installation errors, outdated software, or synchronization issues.

Solution: The Windows app and authenticator are crucial for access. Refer to the official partner documentation, which often includes PDF-Anleitung (PDF instructions) and Videoanleitung (video instructions) for proper installation and setup. Reinstalling the app or resynchronizing your authenticator might resolve the problem. If problems persist, consult your partner support channels.

⚠️ Portal Functionality Issues

Cause: Temporary system glitch, connectivity problems, or browser compatibility.

Solution: If a specific feature isn't working, first ensure you have a stable internet connection. If other parts of the portal are accessible, the issue might be temporary. Try clearing your browser's cache or using a different supported browser. Note that some critical activation systems like ePOS and Activate360 have direct links and can be accessed independently if PartOS itself is down.
