Why passphrases work
A string of random words is both easier to remember and, at enough words, stronger than most typical passwords — because total length drives security. This generator picks words with your browser's secure random source; nothing is sent anywhere. For maximum strength use 6+ words. (Our word list is compact for memorability; for the highest-entropy diceware, use a dedicated 7,776-word list.)
