Facts on WAYF

  • With WAYF, you log in at your academic institution in order to gain access to a restricted web service outside of the institution's own login system — as indicated on the above figure and detailed here.

  • WAYF makes it easy for an institution to share a restricted web service with other institutions, or to use a restricted web service operated outside of the institution's own login system.

  • WAYF makes a large number of prospective, verified users available to the provider of a restricted web service, and saves him the trouble of maintaining login credentials for his users — effectively outsourcing this to the users' academic institutions.

  • WAYF correspondingly saves the staff and students the trouble of having to remember distinct credentials for each web service they access outside of their institution.

  • On the basis of user information transferred from the user’s institution on each login attempt, the service provider determines whether the user should be granted access to the service.

  • Whenever a user attempts to access a web service, WAYF transfers only the minimum of information about him necessary for the service provider to be able to deliver the service to him.

  • WAYF does not store the user's personal information permanently, only for a few milliseconds whenever he attempts to log into a web service connected to WAYF.

  • In terms of personal data protection law, WAYF is data processor on behalf of each identity provider and service provider connected.

  • Due to the particular technical architecture of WAYF, every web service connected is able to receive logins from an array of many different identity providers, Danish and foreign ones alike.

Identity across

If you experience difficulty logging in through WAYF, you must contact your own organisation's IT help desk for assistance. We are, unfortunately, not able to help you. Identity and service providers may contact us directly.


WAYF is a member of REFEDS, the international organisation for identity federations within research and education.
