Why diceware? Memorable phrases of random words have huge entropy and are easier to remember than gibberish like “X#9mP$qZ”. A 5-word phrase has more entropy than a 10-character random password with mixed case + symbols.
🔒 All randomness comes from crypto.getRandomValues() in your browser. No words, passphrases, or any data are sent anywhere.
