Need unique IDs? This mints them from a cryptographically secure random source — never Math.random — in v4, or v7 when you want time-ordered values. Generate in bulk, toggle case and hyphens, then copy or download the list. Just keep in mind that UUIDs are identifiers, not secrets.
UUID Generator runs locally using your browser's built-in cryptography, so passwords, keys and hashes are never uploaded or logged.
Yes. We use the Web Crypto API's secure random source, never Math.random.
No. A UUID is an identifier and may be exposed in logs or URLs; use a proper secret for authentication.
v4 is fully random; v7 is time-ordered, so generated IDs sort roughly by when they were created.
