OpenID Explained. Computers: Security: Authentication: Single Sign-On: OpenID. OpenID Foundation website. OpenID. OpenID is an open standard and decentralized authentication protocol. Promoted by the non-profit OpenID Foundation, it allows users to be authenticated by co-operating sites (known as Relying Parties or RP) using a third party service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to login to multiple unrelated websites without having to have a separate identity and password for each.[1] Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign onto any website which accepts OpenID authentication.
The OpenID protocol does not rely on a central authority to authenticate a user's identity. Moreover, neither services nor the OpenID standard may mandate a specific means by which to authenticate users, allowing for approaches ranging from the common (such as passwords) to the novel (such as smart cards or biometrics).

oAuth End Points Cheat Sheet by kayalshri. oAuth demo. OAuth / OpenID Guides. OAuth. OAuth Community Site. OAuth. For MediaWiki's (the software used by Wikipedia) OAuth support, see mw:Help:OAuth OAuth is an open standard for authorization, commonly used as a way for Internet users to log into third party websites using their Microsoft, Google, Facebook or Twitter accounts without exposing their password.[1] Generally, OAuth provides to clients a 'secure delegated access' to server resources on behalf of a resource owner.
It specifies a process for resource owners to authorize third-party access to their server resources without sharing their credentials. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner. The third party then uses the access token to access the protected resources hosted by the resource server.[2] OAuth is a service that is complementary to and distinct from OpenID.
