OAuth is an authorization protocol, rather than an authentication protocol. Using OAuth on its own as an authentication method may be referred to as pseudo-authentication. [26] The following diagrams highlight the differences between using OpenID (specifically designed as an authentication protocol) and OAuth for authorization.
The diagram from [5] (see right) highlights key additions that UMA makes to OAuth 2.0. In a typical OAuth flow: A resource owner (RO), a human who uses a client application, is redirected to an authorization server (AS) to log in and consent to the issuance of an access token.

Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
OpenID Connect (OIDC) is an identity layer on top of OAuth. In the domain model associated with OIDC, an identity provider is a special type of OAuth 2.0 authorization server. Specifically, a system entity called an OpenID Provider issues JSON-formatted identity tokens to OIDC relying parties via a RESTful HTTP API.
Shibboleth supports a number of variations on this base case, including portal-style flows whereby the IdP mints an unsolicited assertion to be delivered in the initial access to the SP, and lazy session initiation, which allows an application to trigger content protection through a method of its choice as required.
Indeed, the flow outlined in the previous section is sometimes called the Lightweight Web Browser SSO Profile. Alternatively, for increased security or privacy, messages may be passed by reference . For example, an identity provider may supply a reference to a SAML assertion (called an artifact ) instead of transmitting the assertion directly ...
The OpenID logo. 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 identity provider (IDP) service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to log in to multiple ...
