Eduroam allows users from participating institutions to gain secure access to wireless network access using their standard username (email format)/password credentials as they do at their home institution for wireless access.
Eduroam is based on a federated authentication model where your username and password are validated at your home institution (identity provider) and access to authorised network services are controlled by the visited institution (service provider).
Over 20 Australian universities participate in eduroam, eduroam is being deployed at hospitals to assist medical researchers.
