    Well Lucky, remember that there are only 10000 4-digit PINs (0000-9999). It may take awhile to cycle through them all, but not all that long, especially if you have electronic assistance. Many (not all) systems that require a 4-digit PIN will timeout for awhile after some number of invalid entries, but that only slows the process down. It doesn't stop it, unless they also lock the account after too many invalid entries. My guess is that most don't do that, simply because they think it will "inconvenience" their paying customers...
    Sometimes, real fast is almost as good as real time.

    My bank locks it after 3 attempts. You then have to apply for a new PIN which is sent to your home address through the post.

    When do we want 'em?
    Doesn't really matter does it!?

    Same same with our Credit Union, (we gave up using banks a long time ago, unfriendly management and tellers).

    Only difference. I can walk in to reset pin (a few blocks away).

    Great article, I can't believe people actually use "1234." Humorous in a depressing way haha
    Loved the XKCD comics

    By the way, this reminds me of a something similar I read once about Hangman.

    Using "1234" could be considered reverse psychology, some would think that surely no one would use that.

    Hmmm. Well, I'm not going to jump on the bandwagon anytime soon.
    Reverse psychology never works for me when I want it to...

    I am curious though... Realistically, what is the most likely way to get your password "stolen"?
    I don't see how many logon servers would allow for the kind of guessing through sheer processing power by entering every possible combination, and companies would be hurting pretty badly if the most common way for the consumer to get their password stolen would be by hacking the company's password database. My guess, as of right now, is that the most common way for you to lose your password is due to personal error, or just stupidity.

    Hmm. I'm wondering what you guys think (or know).

    This guy has an interesting list, I guess I wasn't too far off (according to him anyway).
