Frequently Asked Questions
What is the difference between Standard and Secure random?
Standard random uses `Math.random()`, which is fast but pseudorandom and potentially predictable. Secure mode uses `window.crypto.getRandomValues()`, which connects to hardware-level entropy for true cryptographic security.
How many numbers can I generate at once?
Our tool is optimized for performance and can generate thousands of numbers in milliseconds. We've capped the UI display for smoothness, but you can export large batches via CSV.
