How to Unlock Windows Laptop with Mi Band 4

What I most like about today’s advanced technology is support for cross-platform integration. Let me simplify it. It means we can integrate different devices and control one gadget using the other. It makes the user experience more simplistic and sophisticated at the same time. The term cross-platform denotes different operating systems. For instance, do you know you that you can unlock Windows laptop using Xiaomi’s Mi Band smartwatch.?

Sounds interesting right.? In this guide, I will explain how you can do it. Rest assured that you do not have to hack, root or modify any device to use this feature. This feature is officially supported by the Mi Band smartwatch. Recently, Xiaomi rolled out a new firmware update for the Mi Fit App. The latest upgrade with build 4.0.17 now allows the Mi Band user to unlock their Windows Laptop using the smartwatch. Let’s see how we can accomplish this.
