Frequently Asked Questions: UUID / GUID v4 Batch Generator

Answers to common questions regarding inputs, calculations, and mathematical methodology.

What is the probability of a UUID v4 collision?

Effectively zero. Generating 1 billion UUIDs per second for 100 years yields an infinitesimal probability of a collision.

Are these UUIDs cryptographically secure?

Yes. They are generated using the browser's crypto.getRandomValues API, backed by operating system CSPRNGs.
