How does eduroam work?

eduroam is a worldwide federation of RADIUS servers that facilitates network access for roaming academic affiliates. eduroam is built with IEEE 802.1X and RADIUS (Remote Authentication Dial In User Service) network protocols. These established technologies are well understood, easy to manage standards and are often already deployed within the network infrastructure of educational institutions.

User credentials are not revealed to the institution at which an eduroamer joins, but instead are only revealed to their home institution, providing an extra measure of comfort for visiting users.

The eduroam network provides a simple and automatic guest provisioning system. Instead of providing a separate visitor network with the added administrative overhead of maintaining user lists, potentially with manual expiration dates, a participating institution may rely on a visitor's home institution to authenticate themselves for the duration of their stay.
