Each purchased Chromebook license allows management of one Google Chromebook user. You must purchase a minimum of 25 Google Chromebook user licenses and can have these EMS licenses for a maximum three year term. You can specify the number of Google Chromebook users and the term duration at time of purchase. FortiClient EMS uses one license seat per logged-in user. If the user logs out, the license seat times out (default timeout being 24 hours), and the license is released. At this point, another user can use this license seat.
If the number of Chromebooks that the EMS is managing exceeds the number of Chromebook licenses available, EMS licenses the additional Chromebooks using any available zero trust network access (ZTNA) licenses. For example, consider that your EMS instance has 50 Chromebook licenses, but 80 Chromebooks connect to the EMS instance. EMS licenses 50 Chromebooks using the Chromebook licenses, and licenses the remaining 30 Chromebooks using 30 ZTNA licenses, if available. EMS only licenses Chromebooks using ZTNA licenses if no Chromebook license is available. See Windows, macOS, and Linux licenses for information about the ZTNA license.
EMS sends you an email when you are running out of licenses. Additionally, a log entry is entered when a client is refused connection due to unavailable licenses.
