Eduroam allows any user from an eduroam participating site to get network access at any institution connected to eduroam. Depending on local policies at the visited institutions, Eduroam participants may also have additional resources at their disposal.
The user credentials are kept secure because eduroam does not share them with the site you’re visiting. Instead they are forwarded to the user’s home institution, where they can be verified and validated.
The system uses a network of servers run by the institutions, and the participating National Research and Education Networks (NRENs) to securely route these requests back to your home institute. All this happens seamlessly and virtually instantly – all thanks to Eduroam!
