Frequently asked questions
- Is the randomness cryptographically secure?
- When the browser supports it, numbers come from crypto.getRandomValues — the same source used for TLS keys.
- What does unique only do?
- It guarantees no repeats, like drawing names from a hat. Useful for raffles, teams and lottery-style picks.
- Can I generate thousands at once?
- Up to 1,000 per draw. The list is easy to select and copy for spreadsheets.
