Request for Comments: 6749 Microsoft Obsoletes: 5849 October 2012 Category: Standards Track ISSN: 2070-1721 The OAuth 2.0 Authorization Framework Abstract The OAuth 2.0 authorization framework enables a third-party application to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing the third-party application to obtain access on its own behalf.
