# Session Configuration

The `session.php` file contains settings related to user and operator sessions. This document provides a list of configuration items available in the file, allowing you to modify them as necessary.

A file `/config/production/session.php` will exist after installation and should be used to update the configuration, as per [Updating Config Files](Updating+Config+Files).

   Name Description Valid Value(s)   `single_session` By default operators can be logged in on multiple devices at once, however you may want to let them only use one device at a time, logging them out of others immediately. If so, set this value to `true`.
