How to Set Up Windows Dynamic Lock to Auto-Lock When You Step Away

Tap a step to see how it works.

  1. Pair your phone with your PC over Bluetooth

    Go to Settings > Bluetooth & devices, click Add device, and pair your phone β€” the device you always carry β€” with your PC over Bluetooth. Dynamic Lock uses this connection to judge whether you've stepped away.

  2. Open Dynamic Lock in sign-in options

    Go to Settings > Accounts > Sign-in options and scroll down to find the Dynamic Lock section.

  3. Turn on Dynamic Lock

    Check the box for "Allow Windows to automatically lock your device when you're away" to enable the feature.

  4. Walk away with your phone to test it

    Carry your phone out of Bluetooth range of your PC, and your screen will lock automatically within about 30 seconds after the connection drops.

  5. Why it's useful

    You don't have to remember to press the lock shortcut every time you step away β€” simply walking off with your phone locks the screen automatically and improves security.

  6. What to check if it doesn't lock

    Dynamic Lock won't work if Bluetooth is turned off or your phone has become unpaired, so check your Bluetooth connection first.

For anyone who forgets to lock up every time

If you keep forgetting to hit the lock shortcut every time you step away from your desk at work or a cafΓ©, your screen can sit unlocked for a while β€” turning on Dynamic Lock means simply walking away with your phone locks it automatically.

Frequently Asked Questions

Does Dynamic Lock lock the PC instantly?

No β€” it doesn't lock the moment the Bluetooth connection drops; there's roughly a 30-second delay, so stepping away very briefly may not trigger it.

Does it work if I pair Bluetooth earbuds instead?

Dynamic Lock is normally paired with a device you always carry, like your phone; you can pair earbuds too, but it's important to choose a device you'll actually have with you when you leave.
