Yes, Cortex 365 licenses are concurrent and not named. This means you can set up as many authorized users as you want with access to the system. However, once all the licenses are in use, another user cannot access the system until a license becomes available. For example, if you own three licenses of Cortex 365 and ten users are authorized, only three users can be logged into the system at a time. When a user logs out, a license frees up for another user to log in.
