SQRL: A new method of authentication with QR codes

Steve Gibson is a known security enthusiast and is behind many projects online such as ShieldsUP! and the Security Now! podcast. He can be a controversial figure, but in the past few weeks, he has introduced a brand new authentication system which is starting to gain traction, and approaches the login issue from a completely different way. It's called SQRL, or Secure QR Login. From the user's side, it couldn't be easier. A site that implements this system would simply present a QR code, and anyone who wants to log in would scan it with a phone app, or a desktop app, and then the site would log them in. No username, no password, nothing to type in.
