Why a passphrase?

A handful of random words is easier to remember and harder to crack than a short, complex password.
A passphrase chains together several unrelated, randomly-chosen words. Because the strength comes from the number of words rather than obscure symbols, it's far easier to remember and type — yet a six-word passphrase carries roughly 77 bits of entropy, well beyond brute-force reach.
Each word is drawn from the EFF large wordlist (7,776 words ≈ 12.9 bits per word) using your browser's cryptographic random source (crypto.getRandomValues with rejection sampling, so there's no bias). The wordlist is bundled with the page and loaded on demand — nothing is fetched, generated or stored on a server.
