OpenID Connect is a well established authentication and authorization technology that is based on the OAuth2 protocol. It is undoubtedly the fastest and most convenient method of authentication for people, and now it is available with Freja eID.
While the specific technical details are somewhat complex to explain is simple terms, the important thing to understand is that there are several actors:
- resource owner – the user who wishes to access your service/website
- client – your service/website/application
- authorization server – Freja eID server
- resource server – the API of the service your user is trying to access
This back and forth between systems makes authentications through OpenID Connect extremely safe when it comes to security, and quick for the end user.
