How to automatically unlock your Chromebook when your Android phone’s nearby
Google is working hard to kill the password. If you want to live in that future now, you can turn on a feature that automatically unlocks your Chromebook whenever you wander near it with your Android phone in your pocket.
The feature’s dubbed Smart Lock, and it recently made its way into the stable version of Chrome OS. Smart Lock uses Bluetooth to connect a Chromebook with your Android phone. When the devices are paired, users can log into their laptops just by pressing a button whenever their (unlocked) Android phone is within range.
