This article describes how to implement a RADIUS server on the UniFi Controller.

UniFi allows you to manage your network in every location no matter how remote, and with RADIUS you can use the same login at each site. RADIUS (Remote Authentication Dial In User Service) is a popular network protocol that provides for the AAA (Authentication, Authorization, and Accounting) needs of modern IT environments. RADIUS equips administrators with the means to better manage network access by helping to provide a greater degree of security, control and monitoring. In basic terms, RADIUS allows remote users connecting to a wireless network to identify themselves and subsequently receive access to what they require.
Starting with controller version 5.5.4, users can now implement a RADIUS server from the GUI, provisioning a config to run freeRADIUS on the USG. Follow the steps below to learn how.
