What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit value used as an identifier. UUID v4 is randomly generated, making collisions extremely unlikely. Widely used as database primary keys, API resource IDs, and correlation IDs in distributed systems.

Is this UUID generator secure?

This generator runs entirely in your browser using the Web Crypto API. No identifiers are sent to any server.
