Frequently asked questions

What is a UUID?

A Universally Unique Identifier is a 128-bit value used as an ID that's practically guaranteed to be unique without a central authority.

Are collisions possible?

In theory yes, but the odds for random (v4) UUIDs are so astronomically small that collisions are effectively impossible in practice.

Are these UUIDs random and private?

Yes. They use cryptographically secure randomness and are generated entirely in your browser.
