Settings

In this release, Microsoft is officially introducing Dynamic Lock, which is a new feature that automatically locks your device when you’re not around based on the proximity of a Bluetooth-paired phone.

When your Bluetooth-paired phone is not found near your device, Windows 10 turns off the screen and locks the PC after 30 seconds.

To enable Dynamic Lock, you must connect your phone via Bluetooth to your Windows 10 PC, and then go to Settings > Accounts > Sign-in options and turn on the toggle switch for Dynamic lock.
