Unlock Chromebook with your Android phone via Smart Lock. Here's how!

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 smartwatch.

With your phone and Chromebook connected, here's how Smart Lock will work the next time you wake your computer up from sleep mode.

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.

Make your Chromebook feel like home

While any Chromebook — or even any Chromebox — can take advantage of this Smart Lock feature, if you're still relatively new to the Chrome ecosystem, one of the best Chromebooks on the market makes for a perfect intro device that you can use as a backup laptop or a couch companion tablet: the Lenovo Chromebook Duet. The Duet might not be as powerful as say the Acer Chromebook Spin 713 or the Lenovo Flex 5, but it's got enough for light work, homework, and for your Reddit browsing while on the couch this weekend. It also comes with a detachable keyboard and kickstand cover, which you can ditch if you want to just sit around all day reading e-books and comics on that bright 10.1-inch 1080p screen.

Practical and pretty

• $250 at Best Buy (128GB)
• $249 at Walmart (64GB)
• $290 at Lenovo (64GB)

Part tablet, part laptop, the Duet is all-awesome.

The Duet finally gives us the kind of Google tablet we've wanted for a decade. If you've been wanting a Chromebook to test the Chrome OS waters with, the Duet is a perfect companion device before you decide whether to buy one as your primary computer.

If you're reading Android Central, chances are you already have an awesome Android phone — and any modern Android phone will work with your Chromebook for Smart Lock — but if you don't, get almost a flagship experience without spending flagship money with the Google Pixel 4a. Google's latest features and quick updates, not to mention one of the best camera experiences on any phone today, make this $350 phone an absolute steal. Oh, and unlike most recent phones, the 4a is a phone you can comfortably use one-handed.

If you're new to Android, this phone is the best place to start. Between a cleaner software experience, best-in-class camera, and three years of swift updates, why would you buy anything else? If you're on AT&T, this is also one of the only unlocked phones to support Wi-Fi Calling.
