Get Free Login Credentials

classEx is provided as a free service by the University of Passau. In order to run your own games, you need login data to login at 

In order to get a login please write us at or use the form at this page.

Next to your personal data, please provide the following information:

  • Course name: This name will be displayed at the login for participants together with the institutions name (e.g. Passau | Macroeconomics). It can be changed later.
  • Institution: Please provide the institution you are working for. The institution will be displayed together with the course name so that participants can find your course.
  • Country: Please provide the country of your institution.
  • Interface Language: Please select the language of the interface. This can be changed later. The language is the same for you and your participants.

Login requests will be processed manually as classEx is still running in a beta version. Normally we proceed applications within 3-4 working days. In some cases, it may take a little longer.

We will try to provide them to you as soon as possible. If you have any questions, please contact us at

The terms of use can be found here.
