FAQ
- Is this a full security assessment?
- No. It is a heuristic check and does not account for breach reuse or advanced entropy models.

- No. Evaluation runs locally in the browser without server-side password storage.
- Why can a seemingly strong password score lower than expected?
- Missing length or character-class criteria can keep heuristic scores conservative.
