What is a UUID?
A 128-bit identifier written as 32 hex digits in five groups. Version 4 UUIDs are random, and collisions are practically impossible.
Are these UUIDs secure?
They come from the browser’s secure random source, so they are hard to guess. Still, use a server-side generator for production secrets.
