Overview#OpenID Connect Authentication Response is an OAuth 2.0 Authorization Response message returned from the OpenID Connect Provider's Authorization_endpoint in response to the Authentication Request sent by the Relying Party.
Only if the Authentication Request was successful and:
- Authorization Server Authentication of the End-User was successful
- Authorization Server Request End-User Consent-Authorization was successful
When using the Authorization Code Flow, the OpenID Connect Authentication Response MUST return the parameters defined in Section 4.1.2 of OAuth 2.0 RFC 6749 by adding them as query parameters to the redirect_uri specified in the Authorization Request using the application/x-www-form-urlencoded format, unless a different Response Mode was specified.
- Access_token - Which can be used to obtain more claims from the userinfo_endpoint
