Answer
B. An authentication mechanism that allows a user to utilize one set of credentials to access multiple domains
Explanation
Federation in identity and access management refers to the ability to use a single set of credentials (username and password) to authenticate and gain access to multiple systems or domains within an organization or across different organizations. This allows users to seamlessly access various resources without the need for separate logins for each system, improving user experience and productivity.
Federation typically involves the use of open standards like Security Assertion Markup Language (SAML), OAuth, or OpenID Connect to facilitate the secure exchange of authentication and authorization data between the identity provider (IdP) and the service providers (SPs). The IdP authenticates the user and issues a security token, which is then trusted by the SPs, granting the user access to their resources based on the provided credentials.
