Can an access token contain claims?
JSON Web Token (JWT) access tokens conform to the JWT standard and contain information about an entity in the form of claims. They are self-contained therefore it is not necessary for the recipient to call a server to validate the token.
What is ID token claims?
The ID Token is a security token that contains Claims about the Authentication of an End-User by an Authorization Server when using a Client, and potentially other requested Claims. The ID Token is represented as a JSON Web Token (JWT).
How to get an ID token from OpenID?
The OpenID authentication request to get an ID token from the IdP for the end-user can also specify which claims the client application is interested in. The preferred method of claims delivery — at the UserInfo endpoint or with the ID token, is determined from the request.
How to receive released claims from the OpenID Connect provider?
There are two ways for a client application to receive released claims about the logged in user from the OpenID Connect provider — at its UserInfo endpoint or included in the ID token. By making a request to the userinfo endpoint of the IdP with a valid OAuth 2.0 access token that was previously issued to the client for the given user.
What are the main considerations of OpenID Connect?
Considerations include the type of application (like web-based or native mobile app), how you want to validate tokens (in the app or in the backend), and how you want to access additional identity information (make another API call or have it encoded right into a token). There are three primary flows: Authorization Code, Implicit, and Hybrid.
Where does authentication take place in OpenID Connect?
Authentication must take place at the identity provider, where the user’s session or credentials will be checked. For that a trusted agent is required, and this role is usually performed by the web browser. A browser popup is the preferred way for a web application to redirect the user to the IdP.
