In the grab bag of Google/Alphabet's big projects for 2016 is Project Abacus. It's basically the company's plot to kill the password in cold blood, by replacing it with smartphone user authentication via an uncrackable collection of biometric readings.
Abacus would lock or unlock devices and apps based on a cumulative "trust score" -- as your phone continually monitors and recognizes your location patterns, voice and speech patterns, how you walk and type, and your face (among other things).
