eduroamCAT for Windows

These settings only apply to students and employees of the TUHH. Students of other universities please use the settings of their university, also with us at the TUHH.

If, as an admin, you want to change the eduroam settings on a device for multiple users in the course of the configuration change, please note that you must manually import the DFN-Verein Community Root CA 2022 certificate in the local machine certificate store.
The certificate installation via the eduroamCAT is not sufficient.
