FAQ
Is this safe for real accounts?
Yes. Every character is drawn from crypto.getRandomValues with rejection sampling — no biased Math.random.
What do the entropy bits mean?
Roughly: 60+ bits resists online attacks, 90+ is strong, 128+ is excellent. It measures brute-force difficulty, not password quality of dictionary words.
