An identity broker is an intermediary service that facilitates the authentication and authorization of users across multiple applications using single sign-on protocols.
Description
In the context of Single Sign-On (SSO) protocols, an identity broker acts as a mediator between users and various identity providers (IdPs) or service providers (SPs). This means that when a user wants to access an application, the identity broker verifies their identity and provides the necessary tokens or credentials, enabling seamless access to multiple services without the need for multiple logins. By centralizing user authentication, identity brokers enhance security, reduce password fatigue, and improve user experience. Examples of identity brokers include services like Okta and Auth0, which support various SSO protocols such as SAML, OAuth, and OpenID Connect. These platforms allow organizations to manage user identities, enforce access policies, and integrate with various third-party applications, ensuring a streamlined and secure user experience. The identity broker's role is crucial in modern digital environments where users expect easy access to numerous online services while maintaining robust security measures.
