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
- Choose a format and length, and an optional prefix.
- Set how many tokens you need and click Generate.
- 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.
