Workflow guide

Secure random generators guide for test data

Generate UUIDs, ULIDs, tokens, passphrases, PINs, and fixture identifiers locally for docs, tests, and non-production examples.

Short answer

Use Fileees generator tools to create local test identifiers and example secrets quickly, while keeping production credentials out of any browser-based workflow.

Open Token Generator

Best for

Developers frequently need placeholder identifiers, tokens, and passphrases for tests and documentation, but should not reuse production secrets.

  • Creating local fixture IDs.
  • Preparing documentation examples.
  • Generating non-production placeholder secrets.

Privacy notes

  • Generator outputs are created locally in the browser.
  • Do not paste production secrets into generator pages.

Common mistakes

  • Checking generated placeholder secrets into production config.
  • Forgetting to label demo tokens as non-production examples.

Limitations

  • Generated examples should not replace a production secret-management process.
  • Mnemonic and passphrase outputs should be treated as test-only unless reviewed.

Steps

  1. Choose the generator that matches the fixture type, such as UUID, ULID, Token Generator, or Passphrase Generator.
  2. Generate values locally and copy only the examples needed for docs, tests, or mock data.
  3. Label generated values as test-only when they appear in shared documentation or source fixtures.

FAQ

Are generated values uploaded?
No. Generator outputs are created in the browser.
Are generated secrets production-ready?
No. Treat browser-generated examples as test data unless your security process says otherwise.
Can I generate sortable IDs?
Yes. ULID Generator creates sortable identifiers for fixtures and examples.
Can I generate passphrases?
Yes. Passphrase Generator creates local example phrases for non-production use.
