Generate memorable, high-entropy passphrases from a 2048-word list directly in your browser. Nothing is uploaded, and generated values are never stored.
A passphrase draws whole words from a fixed, public 2048-word list rather than random characters. Each word contributes exactly 11 bits of entropy (log2 2048), so a 6-word passphrase (66 bits) is easier to type and remember than a random password of comparable strength.
Security comes from the number of possible combinations, not from secrecy of the list — the same reasoning as a cipher's key space. An attacker who knows the exact word list still faces 2048^6 combinations for a 6-word passphrase.
The optional trailing number is appended to one random word and adds a small amount of extra entropy; it does not replace the need for enough words.
