Windows 11 includes a clever security feature called “Dynamic Lock.” When paired with a Bluetooth device (like your smartphone), Windows constantly monitors the Bluetooth signal strength. If you get up from your desk and walk away with your phone in your pocket, the signal drops, and Windows automatically locks your computer screen to protect your data from prying eyes.
However, if you have a spotty Bluetooth receiver on your PC, or if you frequently leave your phone on a charger in the next room while you work, Dynamic Lock will constantly trigger false positives. The screen will abruptly lock while you are actively reading a document simply because the Bluetooth connection wavered. You can easily disable this automatic locking feature.
How to Turn Off Dynamic Lock in Windows 11
You can untether your phone from the locking mechanism within the Windows Sign-in options.
- Click the Start button and select the Settings gear icon (or press Windows Key + I).
- In the left-hand navigation pane, click on Accounts.
- In the main window on the right, scroll down to the “Account settings” section and click on Sign-in options.
- Scroll down to the “Additional settings” section.
- Look for a setting named Dynamic lock (with the description “Automatically lock your device when you’re away”). Click it to expand the menu.
- You will see a checkbox labelled Allow Windows to automatically lock your device when you’re away.
- Uncheck the box to disable the feature.
Windows 11 will immediately stop monitoring your smartphone’s Bluetooth proximity. Your screen will no longer randomly lock itself while you are sitting at your desk. Remember, with this feature disabled, you must now rely on standard inactivity timeouts or manually press Windows Key + L to lock your computer when you leave for the day.
