Ensure your smartphone or wearable is paired with your Windows PC via Bluetooth by going to Settings > Devices > Bluetooth & other devices and confirming it shows as “Connected.” 2. Enable Dynamic Lock by navigating to Settings > Accounts > Sign-in options and checking “Allow Windows to automatically lock your device when you're away,” provided a Bluetooth device is connected and your hardware supports Bluetooth LE. 3. Once enabled, Windows automatically locks your PC when your paired device moves out of range and the Bluetooth signal weakens, typically within 30 seconds to a minute. 4. If the option is missing or not working, verify that your Bluetooth adapter supports LE, update drivers, ensure the device disconnects due to distance (not manual disconnection), and check power settings to prevent Bluetooth from turning off to save power, as Dynamic Lock only triggers based on signal loss from proximity, not manual actions.

Dynamic Lock is a handy security feature in Windows that automatically locks your PC when it detects you’ve walked away—using your paired Bluetooth device (like your phone) as a trigger. Here’s how to set it up:

1. Make Sure Your Device Is Paired via Bluetooth

Dynamic Lock relies on a trusted Bluetooth device (usually your smartphone) to detect your presence. First, ensure your phone or wearable is paired with your Windows PC.

• Press Win I to open Settings.
• Go to Devices > Bluetooth & other devices.
• Turn on Bluetooth if it’s off.
• Click Add device and follow the steps to pair your phone or smartwatch.

Once paired, your device should show as “Connected” when it's nearby.

2. Enable Dynamic Lock in Windows

After pairing, you need to enable Dynamic Lock manually—Windows doesn’t turn it on by default.

• Open Settings (Win I).
• Go to Accounts > Sign-in options.
• Scroll down to the Dynamic Lock section.
• Check the box that says:
  "Allow Windows to automatically lock your device when you're away"

If the option is grayed out or missing, double-check that:

• A Bluetooth device is actually paired and connected.
• Your Bluetooth adapter supports the required Bluetooth LE (Low Energy) features.
• You're using a supported Windows version (Windows 10 and 11 support it).

3. How It Works

Once enabled:

• When you walk away with your paired phone, Windows detects the Bluetooth signal weakening.
• After a short delay (usually 30 seconds to a minute), your PC will lock automatically.
• When you return and your phone reconnects, you’ll still need to sign in (via password, PIN, or biometrics), unless you unlock using Windows Hello.

This adds a layer of security without requiring manual locking.

? Tip: Dynamic Lock only works when your paired device disconnects due to distance—not if you manually turn off Bluetooth or disconnect it.

4. Troubleshooting Common Issues

• Dynamic Lock option missing?

  • Ensure you have at least one paired Bluetooth device.
  • Update your Bluetooth drivers via Device Manager.
  • Some older or third-party Bluetooth adapters may not support the required signal monitoring.

• PC isn’t locking?

  • Confirm your phone is actually disconnecting from the PC when you leave.
  • Try re-pairing the device.
  • Check power settings: Bluetooth shouldn’t be turned off to save power.

• Locks too quickly or too slowly?

  • Unfortunately, Windows doesn’t let you adjust the timeout. It’s handled automatically based on signal strength.

Basically, just pair your phone, enable the setting, and let Windows do the rest. It’s a small feature, but useful for keeping your desktop secure in shared spaces.
