Please follow our instructions for generating SSH-Keys using Windows or Linux/macOS.

Access to MOGON is done via two-factor authentication through an app on your smartphone. Please install one of the apps below, which are approved by the HPC group. Other apps may not function properly and we can not provide support if you experience problems with any other app.

  • Once you have set up your SSH-Keys and freeOTP or PrivacyIDEA on your smartphone, please contact us via the ticket system using your ZDV account 1) and arrange a meeting with us.
  • We will contact you via Skype for Business which is available to all university members or we can arrange a video chat via BigBlueButton, if Skype for Business is not available for you.
  • The whole process should take no longer than 10 minutes, if your SSH-Keys are properly setup.
Information about Skype for Business and BigBlueButton can be found on this Article from the ZDV.

Virtual Private Network

  1. Have your smartphone with freeOTP or PrivacyIDEA app installed ready.
  2. Browse to PrivacyIdea and get ready for the login. Browser extensions, such as uBlock, uMatrix and NoScript, probably will prevent the website from functioning properly.

  7. On the page Token ausrollen select TOTP: Zeitbasiertes Einmalpasswort as token. Do not change OTP-Länge and Zeitschritt. Fill in the field Beschreibung and click on Token ausrollen at the bottom of the page.
  8. Scan the QR-Code on your screen with the 2FA app of your choice on your smartphone.
    Do not share the QR-Code with anyone. Employees of the HPC group will never ask you for your QR-Code or other login credentials.
    Do not scan the QR-Code shown below!
  9. The newly created token is initially deactivated and must be activated by an HPC-Admin.
  10. Inform the HPC-Admin of the successful creation of the token, so that he can activate it. As soon as the token has been activated by the HPC-Admin, you can see the status at the Alle Token page.
  11. Done. You should be able to use the 2FA app of your choice to create new TOTPs as necessary for login to MOGON.
