EduID is a user authentication service of domestic educational and research institutions, which aims to enable users to use their own and external IT services by being identified by their own institution. The advantage is that you only have to identify yourself once per session (Single Sign-on), so you can use it quickly and conveniently.
The institutions form an alliance of trust (aka federation) whose members accept each other’s users as identified. The Alfréd Rényi Mathematical Research Institute has joined the eduID federation.
EduID is based on an open standard and is available to any Hungarian academic institution. EduID can be used to provide teamwork even with foreign partners.
