PC World: Google hasn’t been shy in the past about its desire to kill the password, and at Google I/O, the company started throwing punches. The next version of Android will include several ways to unlock a smartphone without having to enter a PIN or lockscreen pattern, a feature dubbed “personal unlocking.” If the user is wearing an Android Wear smartwatch, the phone will unlock automatically, and you’ll be able to set up trusted locations, such as home or work, where a PIN isn’t required, or use a voiceprint to unlock the phone.
The capabilities carry over to Chrome OS; Chromebook users will be able to automatically authenticate themselves via a paired Android phone, unlocking the laptop and logging into your Google account without ever having to bother with a single password.
