  1. Q: Gaahh! I can't remember this!! These passwords are way to complex!

    A: Read Next to writing it down on paper, I also recommend to carry a lighter ;-)

  2. Q: Estimated time to crack a password generated here is totally different from what I've tested!

    A: Good! Yes that is very likely. No one seems to universally agree on this. What I've done here is explained here. You may try different settings, especially the number of guesses per second

NOTE: If the script appears to hang, reduce the minimum password strength (t) or set it to 0.
