Google is developing technology that would give web apps the ability to unlock Chrome OS machines wihout needing a password. According to the new feature, trusted data received from an app via Bluetooth, NFC or USB ports will be able to wake up a Chromebook or Chromebox, should the user in question be close enough. Critics have pointed out that automated authentication might lead to security problems (what if your phone gets stolen?), but the developers behind the scheme have pointed out that more convinient security is more likely to be used in the first place. "The easier it is to unlock a screen, the more likely is that a user will lock it in the first place," the developers said. At the moment, development is being focused on Chrome OS, but it could soon extend to Android.
