Recommendation ITU-T Y.2723 specifies the mechanisms and procedures for employing "The OAuth 2.0 Authorization Framework (OAuth)", defined by the Internet Engineering Task Force, for the scenarios where the role of the OAuth authorization server is performed by a next generation network (NGN) provider.

The companion document, Recommendation ITU-T Y.2724, "Framework for supporting OAuth and OpenID in next generation networks", provides the context, architectural considerations and high-level framework for employing OAuth in NGNs.

This Recommendation specifies the requirements pertinent to the restriction of OAuth option selections, as well as additional requirements that make the use of OAuth consistent with NGN security and identity management requirements.
