UUID v4 generator

Example
Example: UUID v4 · 1–100
Maximum 1,000,000 characters.
How to use this result
Generate one or more random version-4 UUIDs using the browser’s cryptographic UUID function. Use these as sample record identifiers or independent labels in a workflow that accepts UUIDs.
Worked example
a: 2
Two different UUID v4 strings, one per line. Values vary on every run.
Limits and edge cases
Choose a whole-number count from 1 to 100. UUIDs are identifiers, not access permissions or proof of ownership. Random generation makes collisions unlikely but does not establish a global registry of issued identifiers.
