![]() Notes on Using the Different WordlistsĮFF's new long list, referenced in the directions above, is designed for memorability and passphrase strength. If you reuse a passphrase and it ends up being leaked in a data breach or otherwise discovered, it can be used to try to access your other accounts. ![]() Sometimes password databases or websites get compromised. Your passphrase should only be used for a single purpose, and especially should not be used for more than one online account. Other great uses are the passphrase for an encryption key (like your PGP or SSH key), or, especially, for unlocking a password safe or password manager application. The large number of possibilities makes it much harder for someone to crack even if they get ahold of your device and use encryption-cracking hardware. Your passphrase is especially suitable when directly used to encrypt information, like for full-disk encryption on your laptop or mobile device. This is not necessarily true for an online account, where the speed and quantity of guesses will be limited, but it could be true in other cases (for instance, if someone gets ahold of your device and is trying to crack its encryption password). That means short passwords of any kind, even totally random ones like nQ\m=8*x or !s7e&nUY or gaG5^bG, may be too weak, especially for settings where an attacker is able to quickly try an unlimited number of guesses. While the EFF random number generators are not casino-grade dice, we believe that they are sufficiently random for these purposes.Ĭomputers are now fast enough to quickly guess passwords shorter than ten or so characters - and sometimes quite a few more. Passphrases made of randomly-chosen words can be both easy to remember and hard for someone else to guess, which is what we want out of a passphrase. The increased length can allow for a greater number of possibilities overall, even if you use a passphrase made of random words to help you remember it. The word "passphrase" is used to convey the idea that a password, which is a single word, is far too short to protect you and that using a longer phrase is much better. With so many possibilities, this passphrase will be very hard to guess by brute force. This passphrase is one of 221073919720733357899776 (or about 2⁷⁷) alternatives that could have been chosen by this method. The panoramic view, as I tasted the nectar of a precut granny smith apple and banana, deserved a handclap. It might be a story, scenario, or sentence that you will be able to remember and that can remind you of the particular words you chose, in order. Step 6: Come up with your own mnemonic to remember your phrase. Panoramic nectar precut smith banana handclap ![]() When you are done, your passphrase may look something like this: ![]() Step 5: Repeat steps 1-4 five more times to come up with a total of SIX words. Step 4: You will find the word "panoramic." This is the first word in your passphrase, so write it down. Step 3: Open EFF's Long Wordlist to find the corresponding word next to 43463. Step 2: Your results might look like this reading left to right: 4, 3, 4, 6, 3. (On our dice, the EFF logo is equivalent to rolling a one.) Note the faces that come up without looking at the wordlist yet. For most applications, we suggest making a six-word passphrase. We’ll walk you through how to use EFF's Long Wordlist to generate a passphrase. ![]()
