If you really want to confound any potential cracker, write your own encryption algorithm.

Basically, with a login, they are just trying ever combination of password. But, if they do not know even which keyboard type you used, it become much harder, if not impossible. Try typing £ on an american keyboard.

And, you can make an easy encryption algorithm with any good sized book that is on your PC. Just by converting the text into page, line, char numbers, then do a little shifting, and no one will be able to break it. There just becomes too many possibilities to even try.
