At the very heart of enterprise security is the tension between convenience and safety. The business longs for the ease of users, in competition with the demands of security. Authentication is a main theater for this tension, directly impacting the onboarding and login experience. Federated identity is at the forefront in addressing this tension, affording a good user experience without sacrificing security.
Federated identity management (FIM) makes it possible to share a single digital identity across many services. As end users, we are familiar with the experience of logging into an application using an account from a third party: for example, logging into Twitter using your Google account. This is one form of FIM.
