Remove all Eduroam WLAN profiles. The procedure varies from manufacturer to manufacturer.

Holding your finger on the corresponding profile for a few seconds usually displays the desired option. On some devices, the advanced settings have to be called up to change or delete profiles.

2. Step: Install secure institution-specific Eduroam profile with CAT

A few settings and the installation of a security certificate are necessary for a secure connection setup. The latter ensures that your device does not simply trust any (malicious) access point and pass on your login data.

The installation of the certificate and the configuration do not have to be done manually. For this purpose, there is an app called "eduroamCAT" from the publisher "GÉANT" in the most popular app stores for Android (Google Play, Aptoide, F-Droid, ....). Alternatively, the .apk can be obtained from

After running the app, the proper profile for Friedrich Schiller University must be selected.
