PC Lock

PC Lock is a useful application that, when used together with the companion iOS app, is capable of locking your PC when you leave your desk, and then allowing you to log back in with a single key-press.
The program is designed to help you ensure no one can access your computer when you are not around, and it does this by scanning for a transmission sent from your mobile device via Bluetooth. If your phone or tablet moves out of range, the application locks your PC automatically.
In order to set up the desktop application, you first need to make sure Developer mode is enabled on your Windows 10 PC, thus allowing products from outside the Windows Store to be added.
Also, you need to install the PC Lock iOS app on your iPhone or iPad and connect it to your computer via Bluetooth. Once the devices have been paired, you can launch the desktop program and perform the necessary configurations.
As long as all the requirements have been met, and the iOS app is currently transmitting, the program should be able to detect your phone. Once a connection has been established, the application will lock your screen automatically when the mobile device goes out of range.
However, it is worth noting that the PC Lock iOS app only works in background mode if you purchase the PRO version.
Lastly, it is also possible to have the application put the computer in sleep mode when you move away from your desk, which is very useful for laptop owners, as it can help them reduce battery usage.System requirementsThe PC Lock iOS app needs to be installed on your mobile device
