Password length is still extremely important. A completely randomized 8 character length password is still no match for an attacker with the rainbow tables at their disposal. Complexity requirements should still be employed, but having a length requirement of less than 12 characters is not adaquate. I believe the idea expressed by Winshel of length being more important than randomness is a result of these types of precomputed hash attacks.Winshel; Actually, a passphrase is not as secure as a random password. As you probably have heard, "Don't use dictionary words" over and over again. Even compound dictionary words are bad, ie: "firedogdalmation". Compounding dictionary words with spaces, punctuation, and even gramatically correct modifiers in between is really no different than without. It's a very simple substitution to try; "firedogdalmation" and then try "fire dog dalmation", "Fire Dog Dalmation", "Dalmation the Fire Dog", etc. Using compound dictionary words could come back to bite you very quickly, even when used in long phrases.
