Frequently Asked Questions

What is a UUID used for?

UUIDs uniquely identify records in databases, API resources, session tokens, and file names without a central authority.

What is the difference between UUID v1 and v4?

v1 is time-based (contains a timestamp and hardware MAC address). v4 is random — preferred for most use cases for privacy.
