He also created a Password Creation Slide-Tool that lets administrators configure password policy based on the time to crack, the possible technology that an attacker might be using (from an everyday computer on up to a $180,000 password attacker), and the password protection technology in use (from Microsoft Windows System security on up to 100,000 rounds of the cryptographic hash function SHA-1/).
Sweet! Admittedly, I used one of my shortest/feeblest Graham-inspired passwords. And on the subject of submitting precious passwords to a site, I must admit, I tested one I've only used once for a site I haven't been back to since. If somebody wants to go crack my Hoover's access, go have a ball. I should have addressed this question in the post: how safe is it to go submitting your passwords to sites such as this? I derive assurance from the fact that it's under OWASP, but I'm going to shoot Cameron a note and ask him for feedback on this.

Now, what those characters are and how they're arranged can affect the strength of the password. A password containing 13 ones ("1111111111111") can be broken in less than a day, but a password containing 13 random characters will take 654,637,370 centuries to crack, according to Passfault.
So while *in theory* it may take 1903 centuries, in reality, against a computer with barely enough RAM to run Windows 7 well, it doesn't take long at all. The truth is, if your password for a Windows system is less than 15 characters, it's relatively trivial to crack. And if someone has physical access to the system, they don't even need that long to reset it.
You're right, password length is not the only measure of strength. I was referring to the Carnegie Mellon study's conclusion, which was that length was the most important factor. But as others have mentioned, a long, simple to crack password, such as one character repeated a great many times, does not equate to strength.
I believe the authors miss a key point; password changing is not primarily designed to shorten the opportunity to crack it, it is a preventative and correct control to reduce the liklihood of password sharing.
In an ideal world, yes. In ours, hash files are stolen surprisingly often, and it only takes one to screw you up if you're only using one password. For example, a friend I work with had his website's forum logins comprimised, with about 5000 users' passwords and usernames. The passwords were in salted hashes, so it wasn't terrible, but easier passwords could still have been easily cracked.
about10secondsHow long it would take to crack one of those with a dictionary attack, where a whole word is equivalent to one token. This would be a three-token password at best, given that low numbers would be in a dictionary.
But I did test various formats; the 8 digit format required by work vs using the first line of a poem. The results were clear; whatever option I put in that would meet the requirements at work was more easily cracked than the single line of poetry. As a bonus I already know loads of poems so I don't have to learn anything new.
Just tried the Password Evaluation on my work password and got 8878 centuries to crack.I go by the "the longer the password" principle. Password is 14 caharcters/numbers long.Keep up the good work Sophos.Cheers
according to morris, my everyday passwords are ridiculously strong, while all the passwords my boss comes up with can be brute-force cracked in no more than a week. his passwords are old school gibberish, hard for people, easy on machine. my passwords are hard for people and machine. my general purpose for work password would take 812 trillion years to break with a $180,000 hacking machine. it's surprisingly easy to remember. even if i didn't throw all that leet-speak in it should still take about a billion years. 2ff7e9595c
