What is Google Smart Lock and how does it work?

Forget unlocking your phone every single time you use it.

Published onAugust 22, 2023

Google Smart Lock allows you to access your devices much faster when you’re not too worried about security. If you’re at home, you probably don’t want to enter your passcode every time you pick up your phone. However, this feature allows you to switch back to your regular security in public easily. Here’s a quick look at how to use Google Smart Lock and set it up on your Android phone or Chromebook.


Google Smart Lock is a feature that allows you to bypass lock screen authentication based on on-body detection, trusted locations, or trusted device connections. You can set it up on Android by going to Settings > Security & privacy > More security settings > Smart Lock.


Note: Some of the steps in this article were put together using a Google Pixel 7 running Android 13 and an ASUS Chromebook Vibe CX34 Flip running Chrome OS 116.0.5845.120. Remember that some steps might differ depending on your device and software.

What features does it offer?

Google Smart Lock offers a whole host of different features, allowing you to use it in plenty of situations.

On-body Detection: Provided you’ve already entered your pin or passcode once before putting it back in your pocket or bag, Google Smart Lock will not require you to enter it again when you take it back out.

Trusted Devices: This option allows you to select Bluetooth devices you trust. This means that when your phone is connected to these devices, you will not need to enter your passcode to unlock it.

Trusted Places: Here, you will have to create a location that you trust. This could be your home or office, and you won’t need to enter your passcode when you are there.

Voice Match & Trusted Face: These two options are being phased out and are only present on much older Android devices. However, they work by allowing you to set up your voice or face to use your phone without a passcode. The voice match option won’t always leave your phone fully unlocked, but it will allow you to access some of your device’s features.

The pros and cons of Google Smart Lock

Aside from accessing your devices quickly, Google Smart Lock also allows you to share passwords across your devices. Google Smart Lock makes it easy to get into your devices without a screen lock, and you can save your passwords to access your favorite websites and apps quickly.

However, keep in mind this is a security risk in certain situations. It’s OK if you’ve set up your house as a trusted location, and it’s just you or your family at home. However, on-body detection and trusted devices could allow others to access your unlocked phone.

The feature is simple enough to turn off with the settings in your Google account. You can do this on your Chromebook or Android device by going to settings first and then going into your Google account settings.

Google Smart Lock works a little differently on Chromebooks, and it allows you to unlock it simply by connecting to your Android device. You will need to sign in to your Google Account on both devices.

How to set up Google Smart Lock on a Chromebook:

  1. Go into the Chromebook’s Settings.
  2. Go into Connected devices.
  3. Next to your Android device, select Set up.
  4. Select your Android device and click on Accept & continue.
  5. Enter your password. Then hit Done.
  6. Go back to Connected devices.

  8. Toggle Smart lock on.
  9. Once you receive the confirmation message on your phone, choose the options you want to turn on under “enabled.”
  10. Follow any further instructions to complete the setup.


Google Smart Lock only works on Chromebooks running ChromeOS version 71 or newer. You’ll also need Android version 5.1 or later.

No. Smart Lock requires that all devices involved be in the same Google account.

While Google Smart Lock isn’t the safest, we would argue it would be more secure to use Trusted Devices. These are usually linked to Bluetooth devices you carry around, and Bluetooth is a pretty short-range connectivity method. Of course, it’s always safer to use biometric authentication or strong passwords.
