Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier guaranteed to be unique across systems and time. UUID v4 is randomly generated and is the most commonly used version.
Is crypto.randomUUID() truly random?
Yes. The browser's crypto.randomUUID() uses a cryptographically secure random number generator (CSPRNG), making collisions astronomically unlikely.
What's the difference between UUID and GUID?
They are the same thing. GUID (Globally Unique Identifier) is Microsoft's term for the UUID standard. The format and structure are identical.
