UUID version 4
A UUID version 4 is a randomly generated 128-bit identifier with version and variant bits set according to the format. It is often used for database records, test fixtures, and temporary identifiers.
The tool uses the browser's secure random-number generator and creates up to 100 IDs at a time. UUIDs are designed to make collisions unlikely, but your application should still enforce any uniqueness constraints it requires.
