Google is spending money to get rid of passwords.
The company has just bought an Internet startup called SlickLogin which has been working on a way websites can play an inaudible sound which would be "heard" only by an app on your smartphone, that would then send back a signal to confirm your identity using GPS, Wi-Fi or Bluetooth.
All you'd do to log in would be to put your phone next to the computer. SlickLogin hasn't launched the app yet - it was still in the process on getting financial backing.
The company is based in Israel and its founders say they have lots of experience with Israeli military security.
