Google quietly added an insanely cool security feature to Android Lollipop

Even though some Android device makers have already rolled out devices with embedded fingerprint sensors that offer users added security features, Google has yet to make it a core security feature for Android. But Google is still working on its own interesting solutions for temporarily killing the need for a PIN on smartphones, as the company has just added new functionality to Android 5.0 Lollipop that’s not only cool, but also very useful.
