Frequently asked questions

What is a version 4 UUID?

A v4 UUID is a 128-bit identifier whose bits are almost entirely random, making collisions astronomically unlikely. It's the most common UUID type for general use.

Are these UUIDs secure and unique?

They use the browser's crypto.randomUUID API where available, which is cryptographically strong. Duplicates are effectively impossible in practice.
