# Private Mode

Insight provides an option to enable Private Mode during the Teacher and Student installation process. This option, when enabled, requires that both the Teacher and Student machines have a matching Access Token so that they are able to communicate with each other. 

This provides protection against an unauthorized Teacher console being able to take control of systems running the Insight Student application without having the Access Token.

This Access Token can be configured during the installation of the Teacher or Student application, or through the Administrator Settings in the systems.

{% hint style="info" %}
It is important to keep your Access Token secure. Any Teacher console with a copy of your Access Token can potentially view and control Student computers deployed in your environment.
