An eduID is an account for users associated with Dutch education and research. It is yours and exists independent of an educational institution.
You can use eduID to login to several services connected to SURFconext. eduID is also meant for users who do not have an account with an institution or for services where an institution-independent account is useful.
eduID is still under development. In the future, you will be able to use eduID for many more things. For example, you can use eduID after your studies, as an alumnus, or during your studies, if you wish to follow classes at several institutions simultaneously.
