‘Active sessions’ is a security feature, where FreeAgent lists all the places you are actively logged in. This article explains how to access and manage these sessions.
Select 'Settings' from the drop-down menu in the top-right corner and then select 'Active Sessions'.
You can now view all of your active FreeAgent sessions, whether on desktop or the FreeAgent Mobile app. You can log out from an individual session, or from all other active sessions (you’ll remain logged into your current session).
