How strong is strong enough?
Strength is measured in bits of entropy: each bit doubles the number of guesses needed. 60+ bits resists online attacks; 80+ bits is comfortable against offline cracking of a leaked hash; 100+ is overkill for most people. A 20-character mixed password is around 130 bits. Passphrases of 5–6 random words are easier to type and remember at similar strength.
Generation uses crypto.getRandomValues and never leaves your device. Store passwords in a password manager rather than reusing them.
