“eduroam” (education roaming) is a worldwide Wi-Fi service for scientific and educational institutions. You can log in to the “eduroam” network anywhere in the world by using your University of Konstanz access details. Setting up “eduroam” on your devices is easy: simply download one of the configuration profiles (CAT tools) provided by the German National Research and Education Network (DFN), which checks and confirms security features. Please note that setting up “eduroam” without using one of these tools represents an enormous security risk for your login information.
