About version 4 UUIDs
Version 4 UUIDs are randomly generated identifiers. They are useful for many identifier-generation tasks, but they do not provide authorization, prove identity, or replace a database's uniqueness constraints. Generation uses the browser's cryptographic API; this page does not send or store generated values.
