This Windows Setting Locks Your PC when You Walk Away — and More People Should Use It

Microsoft’s Dynamic Lock feature automatically secures Windows PCs by detecting when a paired smartphone moves out of Bluetooth range. Introduced in the Windows 10 Creators Update, it locks the screen within roughly 30 seconds of the phone’s departure. The setting is accessible via Settings → Accounts → Sign‑in options and works on both Windows 10 and Windows 11. While it adds a hands‑free layer of protection, it still relies on the user’s phone being present and the system being idle.
