This module displays a popup to the customer indicating the number of seconds remaining until they are automatically logged out of the system. The following are its features:

• The module can be turned on or off through the Admin Panel.
• The duration of the customer's session is determined by the cookie lifetime settings configured in the Admin Panel.
• An Admin User has the ability to set the specific number of seconds remaining before a user is logged out, at which point the popup will be triggered.
