The OpenID Connect specification adds a new Hybrid flow and adds variants to the existing Authorization Code and Implicit flows. They share the same principle: having openid in the scope and a combination of new response_type values.
|code||Authorization Code Flow|
|id_token token||Implicit Flow|
|code id_token||Hybrid Flow|
|code token||Hybrid Flow|
|code id_token token||Hybrid Flow|
Special Dispatcher classes have been made to dynamically route the HTTP requests to either an OAuth2.0 flow or an OIDC flow. It basically checks the presence of openid scope in the parameters.
