Frequently asked questions
They are RFC 4122 version 4 UUIDs — random identifiers with 122 random bits, generated with a cryptographically strong source.
Collisions are astronomically unlikely. With 122 random bits you would need to generate billions of UUIDs before any realistic chance of a repeat.
Five is a convenient batch for most tasks. Press Run again to generate another five whenever you need more.
A UUID (universally unique identifier) is a 128-bit value used to label database rows, files, events and API resources without a central authority handing out IDs.
This generator produces five random version-4 UUIDs at a time using your platform's secure random source, ready to copy straight into your code or data.
