I built a zero-config, 2FA-secured Screen Time Manager for Linux

Hey guys!

So now that almost all games run pretty much perfectly on Linux, thanks to the incredible progress with Steam/Proton and the Heroic Launcher, our family finally made the jump. We shifted our main gaming rig from Windows to Linux (running Linux Mint for now) and haven't looked back.

However, I quickly ran into a major issue: the lack of robust parental controls. Most existing tools are either abandoned or incredibly easy for a clever kid to bypass by just changing the BIOS clock. I missed the "set it and forget it" nature of Microsoft Family Safety, so I decided to build a Linux-native alternative.

Meet Linux Family Time Manager.

It’s an open-source, system-level solution designed to give parents airtight control over login windows and active sessions without the "jank."

Main Features:

* Airtight PAM Enforcement: It hooks directly into pam_exec.so. It doesn't just "lock" the screen; it blocks the login at the system level before the desktop environment even loads.
* 2FA Authorization: No more shared passwords. Every time extension or schedule change requires a 6-digit TOTP code from your phone (Google Authenticator, Authy, etc.).
* Active Session Sweeping: If the kids are mid-game when their time expires, a background daemon sends a desktop notification and then terminates the session via loginctl.
* Anti-Cheat Logic: It forces the GUI to wait for a verified Network Time Protocol (NTP) sync before allowing logins, preventing bypasses via hardware clock modification.
* Remote Web Dashboard: A mobile-friendly Flask web portal allows you to grant "+1 Hour" or "+15 Mins" bonus time instantly from your own phone/laptop.

It's built with Python, Flask, and shell scripts. Currently tested and working great on Linux Mint, Ubuntu, Debian, and Arch.

I'd love to hear your feedback, especially from other parents who have made the switch to Linux gaming!
