About
OpenID is a decentralized authentication protocol based on OAuth 2.0 that enables applications to verify a user's identity through an external identity provider instead of managing credentials directly.
It adds an identity layer on top of OAuth by issuing ID tokens that confirm who the user is, supports single sign-on across multiple services, and allows retrieval of basic profile information.
RelMeAuth is a proposed open standard for using rel-me links to profiles on OAuth supporting services to authenticate via either those profiles or your own site.
