UUID generator

What is UUID generator?

A UUID (Universally Unique Identifier) is a 128-bit value practically guaranteed to never collide with another one generated anywhere else — used as database primary keys, session IDs, and request-tracing IDs where you need a unique value without a central authority handing them out.

How to use it

Choose how many v4 (random) UUIDs to generate and in which case, then generate — uses the browser's cryptographic random number generator.
