Re: If that's so, then why
So we reach the crux of it, which is that you just don't like anything that refers to XKCD and your'e so determined to hate everything related to Randall Munroe's "opus" that you reject, out of hand, eminently sensible and workable solutions to the whole password problem with the same elitist bullshitting attitude you always seem to have on these forums.
Now here's the affix: I don't work in anything directly related to IT these days. I got out of it, in part, because of people like you throwing your not inconsiderable weight around every chance you got, insulting everyone who wasn't uyou as "luser" waste of space morons who obviously have to be nannied through everything - even when it wasn't true. In fact especially when it wasn't true. You are an arrogant little blowhard who has a little bit of power over his domain (oh ho ho) and refuses to accept that maybe, just maybe you might be wrong sometimes.
What's the biggest single security hole passwords have these days? People writing them down. Why do they write them down? Because they can't remember them. What do we want people to do with their passwords? Remember them and not write them down. On that score alone the regular language phrase is superior to the cryptic nonsense string of characters. People are able to remember phrases because they are semantic. They contain meaning, and meaning is the glue that makes memory stick.
And in terms of entropy it's a winner again. An 8 character password is easier to brute-force than a 32 character one no matter what characters it's made up from. There is no difference between the strings abababab and nGl04$sh when you are brute-forcing and if you have access to hash tables there's no amount of security that can keep you out over even a short period.
So it comes back to blocking that one major hole: the user. Your solution ensures that there will always be a human-readable copy of some large portion of your userbase's passwords available on handy little pieces of paper. The regular language solution provides a way to close that hole.
So as far as I can tell the only reason you have for rejecting it is that you didn't come up with the idea and Monroe did. Which says plenty about you and little about the idea itself.
