Google - We Don't Need No Stinkin' Passwords

Google set to kill passwords by end of this year with 'Project Abacus'. What if your computer or device didn't need a password to verify who you are? What if it could analyze your voice, face, and the way you swipe the screen? We all have unique identifiers that can be analyzed by our devices, with the help of Google engineer created algorithms. Of course, having a computer, or device, or Google, have that depth of knowledge just by the way we look, sound and move is a little creepy. In addition, law enforcement will cheer this development since physical attributes probably aren't protected from search; just like fingerprints. A password, or key, inputted into a device from our brain cannot be forced from us. What do you think? Will the convenience be worth it?
