One thing to avoid when selecting your password is cultural references that are widely known, as in the case of this example. Trustno1 was used by special agent Mulder in the X Files, making it a prime candidate to be found out. If this isn't a problem enough, efforts to
hack into your account will often be carried out by machines with dictionaries which can test the full range of words they have stored. This means that thousands of possible options can be tried out in a matter of seconds. Now they've even caught up with attempts to substitute numbers for letters, so guessing something like no1, is possible.
