Android has always been strict on security, with the classic PIN, password, and pattern gesture lock dominating each version of the OS. Android mixed things up a bit when it introduced the Face Unlock in Android 4.0 Ice Cream Sandwich, but wasn’t very accurate or popular with the crowd. And while other carriers implemented similar features in phones as far back as 2012 with the HTC One X, they were hardly usable.

Now that Android has all grown up with better features than ever before, the Face Unlock feature has also greatly improved, with higher accuracy and better face recognition. So here is a quick guide on how to use Face Unlock in Android without typing in a single thing.

Step 1: Go to Smart Lock in Settings

Open the Settings app on your Android device and scroll down to find the Security Tab. Depending on the device and your software version, there may be a separate “Lock screen” tab in the Settings menu with the Screen lock menu.

Step 2: Set up a Pattern, PIN, or Password lock

Although Face Unlock works with impressive accuracy, you can’t use it in all real-life conditions, such as night time or outdoors. This is why you need to set up any other form of screen lock, which will act as your safety net when you cannot unlock your device with your face.

Devices running Android Marshmallow will not be able to tap on Smart Lock until they set up a pattern, PIN, or password lock first. Once you have set a screen lock, go back to the lock screen settings and you will be able to access the Smart Lock menu.

Step 3: Set up Face Unlock

Tap on Smart Lock and enter your screen lock passcode to access the menu. Smart Lock comprises of different unique ways of unlocking your Android device without entering the password to do so. At the bottom of the list, you will see the “Trusted face” tab, which allows you to add your face to the security lock.

To set up yourself as a trusted face, hold the phone in straight towards the face until the dots align with your face and you can see the following image on your screen:

If you want to use Face Unlock in Android with more accuracy, you can also come face to “Trusted faces” and select “Improve face matching” to add more images of your face in different lighting and looks so that it always recognizes you.

Step 4: Use Face Unlock in Android

Once you have set up your Android for Face Unlock, press the power button and lock your device. Now press the power or home button to light up the screen, and pay close attention to the small icon at the bottom centre of the screen.

When the camera recognizes your trusted face, this icon will change into an unlocked padlock icon. At this point, you can slide and access your device without entering the password at all. The process happens almost instantly, which makes the whole Face Unlock method efficient and more than just a fancy gimmick.
