Hristo Bojinov, a computer scientist at Stanford, and his colleagues, wants you to forget your password. More precisely, he wants you to never really know it in the first place. They have developed a computer program that can implant passwords in a person's subconscious mind and retrieve them subconsciously too.
The technique could make it impossible for, say, a high-security government agent to reveal his password; the agent wouldn't actually know the secret code. Eventually, the use of subconscious passwords could even trickle down to the rest of us. And considering the precarious state of password protection, that probably can't happen soon enough.
