Frequently Asked Questions
What is a UUID v4?
A UUID v4 is a 128-bit identifier generated using random numbers. It's practically guaranteed to be unique across systems without needing a central authority.
Are these UUIDs cryptographically random?
Yes. This tool uses the browser's crypto.randomUUID() API (or crypto.getRandomValues() as a fallback), both of which are cryptographically secure.
