COMMON QUESTIONS
UUID generator: useful answers
Which UUID version is generated?
This tool creates random version 4 UUIDs. It does not generate time-ordered version 7 or namespace-based UUIDs.
Is a UUID a password or access token?
Not by itself. It is an identifier. Design authentication and authorization separately for your application.
