Password security is one of those things I spend a lot of time thinking about. Using these tools, we increase entropy to drive up recovery time, and this increases the strength of our password. (Security experts have confirmed Munroe’s math, according to the WSJ.) But Burr might be exaggerating the negative effects of his password advice, Grassi adds: “He wrote a security document that held up for 10 to 15 years. We shouldn't be using them. The longer it takes to crawl a key space, the stronger the password. Most people can probably point to a password they’ve created that was deemed strong simply because it had a special character like the “!” or “?” symbol and a numeric string like “123.” And when prompted to change a password, who hasn’t altered it only slightly to avoid the hassle of coming up with an all-new code?

xkcd password complexity

“Much of what I did I now regret,” says Burr, who is 72 years old and now retired. Longer passwords, even consisting of simpler words or constructs, are better than short passwords with special characters. A password with a complexity of 62 needs 14 characters to reach our target of 80 bits: log(62^14)/log(2)= ~83.4 bits of entropy. I have two issues with this: no real benefits as stolen passwords are generally exploited immediately, notifying users with details of attempted logins, successful or unsuccessful.

The new NIST standards that were published in June, authored by technical advisor Paul Grassi, did away with much of Burr’s advice.

In our example xkcd comic, 44 bits of entropy is estimated to take 550 years to brute force. Appendix A,” advised people to use irregular capitalization, special characters, and at least one numeral. In theory, I could have grabbed the source for this generator (available in the web page's source code) and just walked through that entire key space in less time.

Traditionally, organisations impose rules on the length and complexity of passwords. Also, it assumes that the breached account cannot be used to facilitate the breach of further accounts – negating the effect of changing the password on the first.

), Make sure your selections are chosen at random. But in today's world, there are still places where we need to use them.

bad guys don't have to use brute force (they probably know more than you think). Personally I use the free and open source KeePass for managing the hundreds of passwords on my work PC. At least you aren't dealing with password storage here, but the first thing that comes to mind with your code is that I could enter an all-numeric password and have it considered "strong" (when in reality it would be a lot weaker than an all-alphabetic password). In this document, aimed at system owners, they address not only the limitations of passwords but also the effects of various password policies on overall security when accounting for real user behaviour! Don't stop using passphrases or diceware. Cryptography tries to measure this randomness by what is called entropy. I would also recommend, other than the initial log in password for your PC, you can use a password manager application to increase security.

Use all the spaces! If you add all possible ASCII symbols, you get a complexity of about 95. The idea is, I guess, that if a user has to change their password regularly it will limit the time that a compromised password can be use. There's this whole other conversation to be had on whether or not we can even properly measure entropy, but that's outside the scope of this article.
