Security Notes

✓ Uses your browser's built-in secure randomness — not a basic random function

✓ All generation happens in your browser — zero server contact

✓ Aim for 80+ bits of entropy for passwords you rely on daily

✓ A 5-word passphrase is ~48 bits — more memorable than a 20-char random password
