How it works
- Randomness comes from
crypto.getRandomValues()with rejection sampling, so every character is uniformly distributed — no modulo bias. - At least one character from each selected set is guaranteed, then the result is shuffled.
- Strength is estimated as length × log₂(pool size). Aim for 80+ bits for important accounts.
