What are Passcode's:
In the simplest terms Passcode's are statements or sentences that remind you of what your Access Code is.
The Passcode is what is displayed on your screen as the Secret Question and the Access Code is what you enter as the answer to the question.
The trick is to construct Passcode's that will immediately remind you of the Access Code required but will not give any clue whatsoever to others.
An Access Code is a word or preferably a number of words made into a phrase or short sentence.
Passcode's are reminiscent of a psychologist mentioning a word or a phrase and asking you to say the first thing that comes into your mind.
