Explanation

Federation allows two or more organizations to establish a trust relationship for sharing authentication and authorization information without merging internal authentication stores. With federation, users from both companies can access resources in the other company’s environment by using their own credentials, typically through a centralized identity provider (IdP). This approach allows the companies to keep their authentication systems separate but still provide seamless access to applications and services, making it ideal for scenarios like mergers where complete consolidation of authentication systems might not be immediate.
