What about encrypting your 'secret' password with normal password? So you get assigned this 30 characters password, which you learn. Then you use normal password (like 'password123' :) ) to encrypt that string. Then when you need to log on, you first type in you normal password to decrypt your 'secret' password, which is then used to authenticate you further. I know, sounds ridiculous, just thinking out loud.

edit: yes, i know, encrypting the key with another string makes it just that tiny little bit secure, technically it's still plain text...
