Frequently asked questions

Which version of UUID?

v4 — random UUIDs generated via the browser's Crypto API (crypto.randomUUID or crypto.getRandomValues).

Are they cryptographically random?

Yes. UUIDs use the browser's secure random source; every new batch is independent and unpredictable.

Can I generate more than 1000?

The UI is capped at 1000 per batch for browser responsiveness. Hit Generate again for another batch.

Are they ever reused?

No batch state is stored. Every click generates fresh UUIDs.
