What Windows Dynamic Lock Actually Does with Bluetooth Devices
Windows Dynamic Lock automatically locks your PC when you walk away by measuring the Bluetooth signal strength of your paired smartphone. The feature uses signal drop-offs to detect your absence, waiting roughly thirty to sixty seconds after you step away before triggering the lock screen.
Bluetooth signal strength determines when the lock activates, meaning the system does not track your GPS location or use high-tech sensors. When you return, the signal strengthens, but you still need to use a PIN, password, or Windows Hello to log back in rather than having the PC unlock automatically.
Windows Dynamic Lock automatically locks your computer screen when you walk away by monitoring the Bluetooth signal strength between your PC and a paired device like your smartphone. When the signal drops below a specific threshold for about thirty seconds, Windows locks the operating system to protect your personal data.
