What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across space and time. They're commonly used as database keys and for identifying resources.

More than a quick uuid generator.
A UUID generator creates unique identifiers for test data, records, fixtures, and integrations. UUIDs are useful when a project needs an identifier that is unlikely to collide with another generated value.
A UUID is an identifier, not a secret or access-control mechanism. Treat it according to the needs of the system you are building and avoid assuming that an unguessable-looking value alone secures a resource.

UUID generator answers.
Useful context before you use the result somewhere important.
Are UUIDs guaranteed unique?
They are designed to make collisions extremely unlikely, but system design should still account for uniqueness where it matters.
Can I use a UUID as a password?
No. Use a proper secret-management and authentication approach instead.
Why generate several at once?
A batch is useful when you are creating test fixtures or sample records.
