Single Sign-On only requires users to enter their credentials once. This information is saved and automatically re-used if additional authentication is required.

A FortiGate supports both Fortinet Single Sign-on (FSSO) and Single Sign-On using a RADIUS server (RSSO).

Bruce has been working with computers, and related technology, since before the World Wide Web was a thing. He has worked in system and network administration. He has even dabbled in technical support. He has made the switch to technical writing as part of his deep, dark and dastardly plan to make the arcane machinations of IT technology more easily understood by the poor folks who use it. That, and the voices in his head told him it was good idea. Never argue with the voices in your head. People will start to stare.
