Dynamic Lock is a Windows 11 feature that locks your computer when a connected Bluetooth device (your phone or wearable device) is out of range. The Dynamic Lock feature will lock your PC automatically even if you forget to use the Windows key + L shortcut when walking away.
Dynamic Lock uses any connected device with Bluetooth, but it’s probably best to use something with a good amount of battery and range, such as your phone. Once your device is out of reach for 30 seconds, Windows will lock the screen automatically
