That is a good suggestion, blacklisted keywords could act the same way as the username parameter does.

I think a good modification on this would be to also consider blacklisted words:

http://www.phpclasses.org/browse/package/2966.html

There’s a couple of text files worth there. The jquery one couldn’t do this because it was javascript, but working in PHP we can.

I just don’t know how we’d modify the score for finding blacklisted/dictionary words.

I found another two password strength checkers and their algorithms based on words dictionary. Try one at http://www.microsoft.com/protect/yourself/password/checker.mspx and one at http://www.itsimpl.com. Please, try it, and write your thoughts. Good Luck! Jetman

Hi Martin, thanks for letting me know of your website. I took a look at it and the “Keyboard Combinations” passwords seem quite interesting although the characters seem to be always picked from left to right, which lowers the overall security - maybe you should consider adding more entropy regarding that subject…

I’ll be posting a algorithm for generating another type of memorable (and sometimes funny) passwords later in the night, check it out.
