BlueLock

Locking your computer when you step away from your desk is a good idea, especially if you don’t trust that other people won’t try to use it without your knowledge. However, you may not always remember to do this, which is where an application like BlueLock can come in handy.

It is a lightweight, open-source utility that can lock your PC automatically when a paired Bluetooth device goes out of range. It is quite easy to configure, despite the fact that it lacks a GUI.

While BlueLock does not come with a GUI, even novices should find the program to be very easy to configure. When it is run for the first time, a console window will be brought up, and you will need to select the Bluetooth device you wish to use.

It is also possible to customize the check interval, should you want the application to perform the verification more often, as well as specify how long it should wait before locking your PC. What’s more, the program can be added to the startup list automatically.

Once the configuration process has been completed, the console window will be closed and the application will continue to run in the background. If the Bluetooth device you have selected is no longer within range, your computer will be locked automatically.

BlueLock is primarily intended to be used with a smartphone, which you normally carry with you and can let the application know you are not at your desk. Of course, your phone’s battery will suffer if Bluetooth is enabled at all times, but there is nothing the program can do about that.

In a nutshell, BlueLock is an interesting application that can be very helpful if you have a Bluetooth device that you always carry with you. It can lock your PC automatically when a selected device goes out of range, and it is very easy to configure.
