FAQ
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across space and time. UUID v4 is generated using random numbers and is the most commonly used version.
Are these UUIDs truly random?
Yes. This generator uses crypto.randomUUID() which relies on a cryptographically secure random number generator built into your browser.
What is the difference between UUID and GUID?
UUID and GUID are essentially the same thing. GUID (Globally Unique Identifier) is Microsoft's term for what the rest of the industry calls UUID.
