Federation
Federation is a way for different organizations to share access to systems securely. Think of it like having a single key (login) that works at multiple buildings. For example, when you use your Google account to log into other websites, that's federation at work. It helps companies work together while keeping their systems secure and making it easier for users who don't need to remember multiple passwords. This approach is sometimes called "Single Sign-On" or "Identity Federation" in job descriptions.
