In computer systems, an access token contains the security credentials for a login session and identifies the user, the user's groups, the user's privileges, and, in some cases, a particular application. In some instances, one may be asked to enter an access token (e.g. 40 random characters) rather than the usual password (it therefore should ...
Where OAuth focuses on delegated access (I, the user, grant Twitter access to my Facebook wall), and identity-centric authorization, XACML takes an attribute-based approach which can consider attributes of the user, the action, the resource, and the context (who, what, where, when, how). With XACML it is possible to define policies such as
Multi-factor authentication (MFA; two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism.
The facts, or claims, are transported in an "envelope" called a secure token. Claims-based identity can greatly simplify the authentication process because the user doesn't have to sign in multiple times to multiple applications. A single sign in creates the token which is then used to authenticate against multiple applications, or web sites.
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. This access token allows the client application to gain API access to the resource server (RS) on the resource owner's behalf in the future, likely in a ...
A user wielding a user agent (usually a web browser) is called the subject in SAML-based single sign-on. The user requests a web resource protected by a SAML service provider. The service provider, wishing to know the identity of the user, issues an authentication request to a SAML identity provider through the user agent.
In computing, a personal access token (or PAT) is a string of characters that can be used to authenticate a user when accessing a computer system instead of the usual password.
CAS then gives the application trusted information about whether a particular user has successfully authenticated. CAS allows multi-tier authentication via proxy address. A cooperating back-end service, like a database or mail server, can participate in CAS, validating the authenticity of users via information it receives from web applications ...
