API Token Generator

4bba9c66671591e513eb8594fe0ffe89

Generated locally with your browser's secure random generator — never sent anywhere.

Developers constantly need random tokens — API keys, session secrets, webhook signatures, password-reset tokens. They must be unpredictable, which means using a cryptographically secure random source rather than Math.random. This free API Token Generator produces secure random tokens in hex, URL-safe Base64 or alphanumeric form, with a configurable length, optional prefix and batch generation — entirely in your browser.

How to use it

  1. Choose a format and length, and an optional prefix.
  2. Set how many tokens you need and click Generate.
  3. Copy a single token, or copy them all at once.

Why use this tool

  • Cryptographically secure randomness (crypto.getRandomValues).
  • Hex, Base64URL or alphanumeric, with prefix and batch.
  • Generated locally — nothing is uploaded.

FAQ

Are the tokens cryptographically secure?

Yes — they use the browser's crypto.getRandomValues, the same secure random source used for cryptographic keys.

What formats are available?

Hexadecimal, URL-safe Base64, or plain alphanumeric — plus an optional prefix like "sk_".

Are the tokens sent anywhere?

No. Everything is generated locally in your browser and never leaves your device.
