Is it possible to log into sites and programs without a username and password?

Episode 1156 (2:20:15)

George from Santa Monica, CA
Password

George wants to know of a way to use his computer without having to use a password or user name because he keeps forgetting them. Leo says that passwords don't work. We have to remember them, so we tend to make weak passwords and use them on multiple sites. Steve Gibson has an idea called SQRL (Secure, Quick, Reliable Log In). The idea being that a smartphone app will automatically authenicate using a QR code so it just lets the user right in. Great idea, but behind the scenes it's a lot more complicated than that. It's going to be a while before anything like this is widely adopted, though.
