How Is Openid Connect Different From Openid 2.0 And How Does It Overcome The Problems Experienced With Openid 2.0?

Answer»

OpenID CONNECT has MANY architectural similarities to OpenID 2.0, and in fact the protocols solve a very similar set of problems. However, OpenID 2.0 used XML and a custom message signature scheme that in practice sometimes proved difficult for developers to get right, with the effect that OpenID 2.0 implementations would sometimes mysteriously refuse to interoperate. OAuth 2.0, the substrate for OpenID Connect, outsources the necessary encryption to the Web’s built-in TLS (also called HTTPS or SSL) infrastructure, which is UNIVERSALLY implemented on both client and server platforms. OpenID Connect uses standard JSON Web Token (JWT) data structures when signatures are required. This makes OpenID Connect dramatically easier for developers to implement, and in practice has resulted in much better INTEROPERABILITY.

The OpenID Connect interoperability story has been proven in practice during an extended series of interoperability trials conducted by members of the OpenID Connect Working Group and the developers behind numerous OpenID Connect implementations.
