Overview

What it is

Proximity Lock System is a Python CLI tool that automatically locks your system when your paired Bluetooth device (like your phone) goes out of range. It continuously monitors nearby devices, ensuring your computer stays secure when you step away.

Intent

I need it when

Set up a lightweight security tool that runs as a CLI service on my Linux/macOS machine

The Python CLI tool installs via pip with minimal dependencies (pybluez), runs as a background service, and provides simple setup and start/stop commands for easy management without GUI overhead.

Automatically secure my computer when I step away without manual intervention

Proximity Lock System monitors your paired Bluetooth device (phone/smartwatch) in real-time and automatically locks your system when the device goes out of range, eliminating the need to manually lock before leaving your desk.

Reduce security overhead by using my existing phone as a proximity trigger

Proximity Lock System leverages your already-carried Bluetooth device as a proximity sensor, eliminating the need for additional hardware or complex security configurations while maintaining automatic protection.

Prevent unauthorized access to my unattended workstation during brief absences

The tool continuously scans for your paired Bluetooth device and triggers system lock immediately upon detection of out-of-range status, providing passive security without requiring user action or remembering to lock.

Drop

Not a fit when

  • User requires commercial support or SLA guarantees for a production security system
  • User's Bluetooth device does not support continuous proximity monitoring or has unreliable range detection
  • User needs cross-platform support beyond Linux/macOS CLI environments
  • User requires integration with enterprise identity management or centralized device management systems
  • User's system lacks Python runtime or pip package manager installation capability
