Overview#OAuth is a an open standard scalable Protocol for Delegation of Authorization to server resources using HTTP
Generally, OAuth is a solution to the Password Anti-Pattern.
OAuth 1.0#OAuth 1.0 is defined by the Informational RFC 5849 in April 2010 and was OBSOLETED by RFC 6749. OAuth 2.0 is an evolution of the OAuth protocol and is not backward compatible with OAuth 1.0. OAuth 2.0 focuses on client developer simplicity while providing specific authorization flows for web applications, desktop applications, Mobile Devices, and living room devices. The specification and associated RFCs are being developed within the IETF OAuth WG; the main framework was published in October 2012.

- Facebook's new Graph API only supports OAuth 2.0.
- Google supports OAuth 2.0 as the recommended authentication mechanism for all of its APIs.
