 This support for *decentralized authentication* allows users to benefit from single sign-on when using their institutional account across multiple platforms and teachers to trust their students' identities when taking high-stakes tests and exams in Dodona.
 
 Dodona automatically creates user accounts upon successful authentication and uses the association with external identity providers to assign an institution to users.
+These institutions can have multiple sign-in methods.
+If a user uses more than one of those methods, these logins are linked to the same user.
+Institutions are also categorized internally in secundary education, higher education, and other (e.g. the Flemish government).
+
 By default, newly created users are assigned a student role.
 Teachers and instructors who wish to create content (courses, learning activities and judges), must first request teacher rights using a streamlined form[fn:: https://dodona.be/rights_requests/new/].
+The sign in page can be seen in Figure\nbsp{}[[fig:whatsignin]].
+After logging in, a user sees an overview of the courses they are registered with.
