Frequently asked questions
What is a UUID?
A UUID is a 128-bit identifier, written as 32 hexadecimal digits in five groups (for example 550e8400-e29b-41d4-a716-446655440000), designed to be unique without a central authority.
What is UUID version 4?
Version 4 UUIDs are generated from random numbers, which makes collisions astronomically unlikely. They are the most common UUID type for IDs in software.
