This is the OpenID Connect Working Group (AB/Connect WG) repository for the original OpenID Connect 1.0 specifications. It is used for tracking issues, discussing enhancements, and maintaining the specifications that define OpenID Connect and some extensions to it. The full list of OpenID Connect working group repositories is available at https://openid.net/wg/connect/repositories/.
