The following diagrams highlight the differences between using OpenID (specifically designed as an authentication protocol) and OAuth for authorization. The communication flow in both processes is similar: (Not pictured) The user requests a resource or site login from the application. The site sees that the user is not authenticated.
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.
Enables OAuth 2.0 implementations to apply Token Binding to Access Tokens, Authorization Codes, Refresh Tokens, JWT Authorization Grants, and JWT Client Authentication. This cryptographically binds these tokens to a client's Token Binding key pair, possession of which is proven on the TLS connections over which the tokens are intended to be used.

The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies.
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 Central Authentication Service (CAS) is a single sign-on protocol for the web. [1] Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once.
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 ...
