A service cannot be connected to WAYF unless it is documented to the WAYF Secretariat that an institution wants to access the Service through WAYF.
The term services refers to web services that already are, or wish to be, connected to WAYF. WAYF connects web services with log-in systems at e.g. educational institutions. In this way web services get access to a wide range of users with one single technical connection — which also makes possible interlinked operations between service providers.
