Every time a user logs in to a Freshworks account on a device, a "session" is created. If you've logged into your account using different browsers or devices, each will be considered as a different session.
Idle session timeout is a security management feature that allows the organization admin to set the duration of time a session can be idle before it is terminated.
A session is deemed to be idle if the user didn’t perform any activity like mouse move or keyboard clicks etc in that Freshworks Account.
Navigate to the Neo Admin Center.
On the left nav bar, click on Security.
Click on Idle Session Timeout, and you will be redirected to the page where you can set the limit.
Note: An organization admin can set the idle time between 5 minutes to 1 hour. Based on the time set, a user will be logged out of all sessions and will have to login again to begin a session. However, a click, or a hover within the defined time frame will also prevent a session from being deemed idle.
Admins can choose to disable the functionality from the same drop down menu.
