About UUID v4
A UUID is a 128-bit identifier represented as a standardized text string. Version 4 UUIDs are randomly generated and are useful when you need identifiers without coordinating a central sequence.
Common uses
- Create fixture IDs for tests
- Generate sample database identifiers
- Prepare mock API payloads
- Create temporary unique values during development
Notes
UUIDs are identifiers, not secrets. They are useful for uniqueness but should not be used as passwords, tokens, or access keys.
