Amazon has specially commended the security of OAuth 2.0; however, the protocol’s developer, Eran Hammer, withdrew from the project in mid-2012, saying that, compared to OAuth 1.0, many compromises had made OAuth 2.0 “more complex, less interoperable, less useful, more incomplete, and most importantly, less secure.”
Give it whirl in your copious free time and let us know what you think.
