About This Tool

The Secure UUID Generator creates version 4 UUIDs using the browser's Web Crypto API — ensuring cryptographic randomness rather than weak pseudo-random generation. Use them as session tokens, database IDs, or API keys in testing environments. Free, no account, generated entirely in your browser.

How to Use

  1. 1

    Set how many UUIDs to generate.

  2. 2

    Click Generate — cryptographically random UUIDs appear in the output.

  3. 3

    Copy individual UUIDs or the full list with one click.
