About UUID Generator
A UUID (also called GUID) is a 128-bit identifier written as 32 hex digits, like 3f2b1c4e-8d6a-4b2f-9c1e-5a7d0e9b4f21. Version 4 UUIDs are random, so you can create them anywhere without coordination and practically never get a duplicate.
Frequently asked questions
Are these UUIDs secure?
They're made with your browser's cryptographic random generator (crypto.randomUUID), the same source used for security keys.
What's the difference between UUID and GUID?
None in practice. GUID is Microsoft's name for the same thing.
