Improve Trusted face security

One of the cooler features of Android Lollipop is the ability to unlock your phone with your face. Google has just added some new features to its Trusted face application to make it even easier to use your face alone to get to the content on your device. You can even change the settings so that your camera is more likely to recognise you in different situations. As well as using your face, you can use smart devices to unlock your Android phone. In this tutorial, we’ll show you how to get the security set up, explain some of the tweaks and let you know some of the problems that Trusted face has. All you’ll need for this tutorial is a device with a front-facing camera that has been updated to the latest version of Android Lollipop. It shouldn’t take more than a few minutes to get everything up and running.


First, you need to enable access for Trusted face. We’re running this tutorial on a HTC One (M8), but the steps will be similar on any device not running vanilla Android. Head to Settings>Security menu. Scroll to Trust agents.


You need to make sure that Smart Lock (Google) is turned on in this menu or nothing will work. Swipe the slider to on, then head back to the Security menu. If there wasn’t before, you’ll now see an option marked Smart Lock.


To get into this menu, you’ll need to enter the pattern, password or pin that you use to unlock your phone. Then you’ll be shown a list of the smart unlock options. Let’s have a look at Trusted face; tap on that option.


You’ll be told the best conditions to scan your face in. Hold your phone at eye level in a well-lit room and put your face in the oval of green dots in the centre of the screen. Once they’re all filled in, you will have completed your first scan.


Once Trusted face is set up, head to the menu and tap the option again. This time, choose Improve face matching. Read the instructions and take different shots using the same method. More shots mean it is more likely to recognise you.


The options menu lets you set different ways of unlocking your device. You can use your registered smart devices or set your phone to remain unlocked while it’s on your person. Remember to have a back-up pattern or pin.
