Blue Lock is a free and open source application for Windows, that monitors the proximity of your Bluetooth phone or device and automatically locks your computer whenever it’s out of range (e.g., you’ve walked away from your computer). The usefulness will depend on the strength of your Bluetooth devices, since it’s not really going to do its job if you’ve got a strong signal and receiver that keeps a connection from across the office. But if it works well with your Bluetooth devices, Blue Lock provides a simple way to keep your computer secure when you step away for a few seconds but forget to hit Win-L.
