OpenID Connect	OAuth 2.0
OpenID Connect is a "profile" of OAuth 2.0 specifically designed for attribute release and authentication.	OAuth 2.0 is an authorization framework, not an authentication protocol. OAuth 2.0 can be used for a lot of cool tasks, one of which is person authentication. This has been designed mainly for autornization.
There is id_token defiend as part of authentication.	There is no id_token defined in OAuth 2.0 because it is specific to federated authentication.
OpenID Connect is laser-focused on user authentication.	OAuth 2.0 was left generic so it could be applied to many authorization requirements, like API access management, posting on someone’s wall, and using IOT services.
