Linux-Kid-Safe

A starting point for hardening your linux install for children and teens so they can not bypass some of your security measures.

I Started this project with the help of Chat GPT on March 12 2026. I know it started with AI but i'd like to get it expanded to be more useful and to be more of a community project.

A simple toolkit for locking down Linux desktops for children.

Danger - At the moment this is a very basic script that only implements a few features. It is not a complete solution and should not be used as-is in production environments. Use at your own risk and always test in a safe environment first.

#Will possibly destroy all users on the system if used incorrectly. Always backup your data before running this script.
