Corporate Passwords!

I love corporate password policies:

Your Password must be between 8 and 20 characters in length. At least one non-alphabetic character is required and spaces cannot be used. Your Password cannot be the same as your Username. It cannot be repeated within a cycle of 5 Password changes. Your Password should be difficult to guess.

"... difficult to guess" - and fucking impossible to remember.

It's time to stop using passwords.  Put a chip in my head please.
