Then activate the connection via the button and enter your uni login data in the following popup. Your own e-mail address is required as the user name here, in the form firstname.lastname@example.org for students. The password is the password of your student account.
Once the app has been installed and configured, the user name and password will be prompted when the app is started or when the connection name is tapped. It is not possible to save the password.
