Q. What is Dynamic Lock used for on Windows 10?
A. When Microsoft introduced Windows 10 almost three years ago, one of the unique features that would be part of the new operating system was Windows Hello, a feature that would use biometrics to allow end users to log into their Windows 10 devices (so long as the device could support the technology).
In last year’s Windows 10 Creators Update, Microsoft added a counterpart to Windows Hello with Dynamic Lock – jokingly referred to as Windows Goodbye – a feature to help to secure your Windows 10 device when you walk away from it.
Dynamic Update uses the proximity of a Bluetooth device such as a smartphone, headset, or any other paired device that you have around your computer to automatically lock your device once the paired item is out of range. For most people, their smartphone is the most likely device that will be used for this purpose, as we all usually pick up our phones as we leave our desks.
The amount of time your paired device needs to be out of range is about one minute according to Microsoft. That will vary depending on the strength of Bluetooth on your paired hardware and other environmental factors in your home or office.
