🔐 How Randomness Works in This Tool

We use JavaScript’s native Math.random() function, then add post‑processing to guarantee the first digit is never zero. That ensures every generated number contains the exact digit length you selected. While this isn’t cryptographically secure for banking, it’s more than enough for educational demos, lucky draws, or quick password ideas.
