Frequently Asked Questions
What makes a UUID 'Version 4'?
An RFC 4122 Version 4 UUID is generated from 122 cryptographically random bits (with 6 fixed bits identifying version `4` and variant `8/9/a/b`), making collisions practically impossible.
Does this require an internet connection?
No. UUIDs are generated locally by your browser's Web Crypto API.
