Whereas OAuth2 doesn't explicitly define which token type to use, OpenID Connect defines an API and data format to perform OAuth2 authorization flows.

What are the occasions in which a JWT is returned in OpenID Connect?

1 Answer 1


Authorization flow: the client requests an authorization code to the authorization endpoint (/authorize). This code can be used againt the token endpoint (/token) to request an ID token (in JWT format), an access token or a refresh token.

Implicit flow: the client requests tokens directly from the authorization endpoint (/authorize). The tokens are specified in the request. If an ID token is requested, is is returned in JWT format.

Hybrid flow: the client requests both an authorization code and certain tokens from the authorization endpoint (/authorize). If an ID token is requested, it is returned in JWT format. If an ID token is not requested at this step, it may later by requested directly from the token endpoint (/token).
