Today’s enterprise employees use an ever-increasing number of applications, both enterprise hosted and in the Cloud, to do their jobs. What’s more, they are accessing those applications from a variety of devices (desktops, laptops, tablets, phones, etc.) and application models (both browser and native). Expecting those employees to remember strong and unique passwords for each and every application is simply unreasonable. Identity federation solves these challenges by providing a secure, private mechanism for organizations to share user identities, removing the need to maintain separate user profiles for every enterprise application.
