What if passwords were more like Guitar Hero?

As anyone who ever played Guitar Hero knows, you might be able to play "Sweet Child of Mine" with your eyes closed, but that doesn't mean you can tell someone the exact sequence of buttons and colors to push. It's ingrained in your subconscious memory.

In the race to find a new way of keeping our information safe, which includes revolutionary password ideas like using one's heartbeat, letting a computer make it up and using typing styles, a new idea has entered the fray: using subconscious sequence recall.

The Serial Interception Sequence Learning (SISL) approach requires a password, but the user will never know what it is.

Hristo Bojinov of Stanford University devised the system that works by teaching you a sequence via repetition, as you would have learned "Sweet Child of Mine" on Guitar Hero.

A user views an interface that looks similar to the Guitar Hero set up and is presented with the option to hit one of six buttons. During a 45-minute, 4,000-keystroke training session, you'll hit the key that corresponds with what's on the screen. During that time, you'll also be learning a 30-key pattern, without ever realizing it.

Later, you'll "play the game" again, but your 30-key sequence will be interspersed with other 30-key sequences. If you perform reliably better on your sequence than the others, voila. You're in.

And there's no reason not to, as it'll be in your subconscious.

This leads to a number of benefits: no one can coerce a password out of you, you'll never forget it and it's at least thousands of times more secure than the average password.

Exciting stuff, but now I just want to play Guitar Hero ...
