OAuth 2.0 is a recent IETF standard devoted to providing authorization to clients requiring access to specific resources over HTTP. It was recently adopted by major internet players like Google, Facebook, and Microsoft. It has been pointed out that this framework is potentially subject to security issues, as well as difficulties concerning the interoperability between protocol participants and application evolution. As the authors show in this paper, there are indeed multiple reasons that make this protocol hard to implement and impede interoperability in the presence of different kinds of client.
