 One-Time Passwords

On Lamp talks about one time passwords.

"There is another authentication system known as One Time Passwords (OTP). As the name suggests, you can only use a password once; you aren't allowed to reuse it. An OTP system ensures that a discovered password is useless to the person who discovers it. This can provide a bit more security in a world that contains password crackers, packet sniffers, and keyloggers."
