How it works
UUID v4 values are random identifiers. They are suitable for test data and application identifiers, but are not a replacement for an authorization system.
Set version and variant bits on cryptographically random bytes.
Common questions
Are UUIDs guaranteed unique?

Can I use these in production?
They are suitable as identifiers, but follow your database and security design.
Independent developer utility. Review output before using it in production.
