Frequently asked questions
What is a version 4 UUID?
A UUID generated from random numbers. The chance of two ever colliding is astronomically small, which is why they are used as unique IDs.
Can I generate many at once?
Click Generate repeatedly for a new one each time. Each is independent and random.
