How to unlock your Chromebook using your Android phone with Smart Lock

Originally called "Better Together", Google's pairing of Android phone and Chromebook allows you to get back into your computer quicker and stay connected thanks to SMS syncing and Instant Tethering. Turning on this connected device feature on your Chromebook is easy, and you should absolutely use it, especially if you're already using Smart Lock to keep your phone unlocked when it's on your person or paired to your smart watch.

How to unlock a computer with Smart Lock

  1. Unlock your paired Android smartphone. If you use Smart Lock on your phone, ensure that it hasn't timed out and re-locked due to inactivity or turning off a connected smartwatch/Bluetooth speaker.
  2. Open your Chromebook's lid.
  3. On the login screen, look at the lock next to your name. The lock will turn green when the Chromebook recognizes your connected phone is unlocked.

  4. Once the lock turns green, tap your profile picture to unlock the Chromebook.

If the lock turns yellow, the Chromebook either couldn't find your connected phone or thinks your connected phone is locked. In either event, you'll have to input your password the old-fashioned way.
