Mobile Authenticator

Setting up two-factor authentication (2FA) on your mobile phone

The authentication process on MOGON provides the best possible protection against malicious intent. Here are step-by-step instructions on how to set up your phone for 2FA.

Prepare your Smartphone for 2FA#

The two-factor authentication to verify personal usage of your MOGON account, requires you to download and install an authenticator app on your smartphone. Please pick one of the two recommended apps below, which are checked for compatibility with our system. Other apps may not function properly and we cannot provide support if you face trouble with a different app.

• iOS:
  • freeOTP
  • PrivacyIdea
• Android:
  • freeOTP
  • PrivacyIdea

If you nevertheless decide to use another app, make sure it supports sha-256.

A VPN is necessary to access privacyidea.zdv.uni-mainz.de . If you have not set up VPN on your PC, yet, please follow these instruction from ZDV. In case you are outside the campus network, and can not use a VPN, please use the following link: 2fa.hpc.uni-mainz.de .

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.
3. This website is only accessible within the campus network. You can reach it from outside via VPN or with a remote desktop session . Users outside of the campus network, which can not use a VPN, can instead go to 2fa.hpc.uni-mainz.de . This link resolves to the same page.
4. For the login you need your username and the one-time registration key. The one-time registration key serves as a password for the login to PrivacyIdea and is sent to you by e-mail after your account has been added to an HPC project.

5. After successful login, click Token ausrollen in the menu on the left side.
6. 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.

7. 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 above!

1. The newly created token is initially deactivated and must be activated by an HPC-Admin.
2. Establish contact with the HPC Group for the identity verification process
3. 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.
4. Done. You should be able to use the 2FA app of your choice to create new TOTPs as necessary for login to MOGON.

Contact the HPC Group#

• Once you have set up your SSH-Keys and freeOTP or privacyIDEA on your smartphone, please via the ticket system using your ZDV account.
• We will send you an appointment for the video call and the link to our BigBlueButton session.
• The call should take no longer than 15 minutes, if your SSH keys are properly set up. Please have your ID or passport ready for verification.

Switching to a New Phone#

Migrating privacyIDEA to a new smartphone requires that your old one is still functional and you can log in to MOGON with it, and that your new smartphone is already set up and functional.
