Earlier quoted context omitted.
A password space of 600,000 options is under 20 bits of entropy. That's basically pointless. If you want 40 bits, you're going to need a little over 1,000,000,000,000.
Sure, but I thought it was obvious you wouldn't use one word. I'm saying a six megabyte file plus a one line shell script is enough to generate secure passwords with just four words by producing something like "Gargantuan Lackadaisical Lugubrious Flibbertigibbet" which while a bit of a mouthful isn't terribly difficult to memorize compared to 76 bits of line noise or even base64.
But that's not what was being discussed. Someone suggested that if one were to use a website that generates passwords, they should use one that generates multiple passwords to pick from to mitigate the risk of the site being malicious and knowing your password. And I'm saying that that is not useful for any practical length of password candidate list.
