This password can be very memorable, because you had a lot of options for just how it should be put together. Put those 13 words into any order you want, with punctuation separating them. Then, choose your favorite 13 of those 15 words, and discard the other 2. I’ve started generating passwords in the following way:įirst, roll 15 Diceware words. And you’re still stuck using all the words you rolled, which limits how memorable your password will be. To guarantee more than 128 bits of entropy, now your password needs to contain 13 words. Pessimistically, your password using this method could have as few as log2(6^5 choose N) bits of entropy, or 107 bits for 10 words. Unfortunately you lose some bits when doing this, and it’s important to take that into account. Instead of choosing N words in order and trying to remember them in the order you rolled them, you might try reordering the words you roll, to give them a more memorable structure. But the passwords I get are often difficult to remember: The words don’t have any semantic structure, and it’s not always easy to come up with mnemonics for lists of ten words. I’ve used this method in the past, and it works well. And if you roll a password with N words in it, you’ll end up with N * log2(6^5) bits of entropy. If you want your password to have 128 bits of entropy (enough for essentially all purposes), you can generate one by randomly choosing ten words from the Diceware list. You sit there rolling dice for a few minutes to choose random words. DicewareĪ respected way to generate secure passwords is by using the Diceware word list.

It’s a good idea to incorporate as many truly random choices into your password as possible, to ensure that it’s really unpredictable. Adding one bit of entropy (one coin flip) to your password doubles the number of guesses required. That means that an attacker who knew your decision procedure would have to guess, on average, 2^(10-1) passwords in order to successfully guess the one you chose. It’s a good illustration of the concept of “entropy”: In the context of security, entropy is a measure of how difficult your password is to guess, and it depends on how you chose the password.įor example, If you choose your password by flipping a coin 10 times, and adding a “1” if you get heads or a “0” if you get tails, your password has 10 bits of entropy. It advocates choosing four random common words as your passphrase, instead of doing the traditional password generation black magic, because these passwords can be harder to guess and easier to remember. If you’re interested in computer security, you have probably seen the “ Correct Horse Battery Staple” XKCD comic. So how do you choose these passwords to be secure and memorable? Entropy You’ll probably also need to memorize your disk encryption password and your user account password for your computer. Ideally you should use a password manager like Bitwarden to store almost all of your passwords.īut of course you can’t store your Bitwarden password in Bitwarden, so it’s still necessary to memorize at least that one password. I'd love to hear from you with any thoughts you have about this site.It’s a good idea to avoid remembering passwords – the more passwords you need to remember, the more tempting it is to re-use them.

While you should never write your passphrase on a piece of paper, if someone did do that, a series random words is less obvious than a traditional password. The best way to keep track of your passwords is with a password manager. What should you do after you create a passphrase?

When you're ready to use your passphrase, just double-click to select it, rather than highlighting and copying it.

You can also add a number or special character, or you can uppercase part of the passphrase.

For instance, if spaces aren't allowed, you can replace them with dashes.

It's easy to adjust your passphrase to meet common requirements.

Many sites don't do this, which makes the newly created password vulnerable to attack.

This site protects your information when communicating between the server and your browser, using HTTPS.

Three words are much easier to remember than a series of random characters, letters and numbers, yet they are much harder to hack.Ĭomputer experts use passphrases whenever possible, and you should, too! What is a passphrase?Ī passphrase as a series of unrelated words that you can use as a password. Use this website to create passwords that are easy to remember but hard to guess.
