Tokens are generated locally with your browser's secure random generator and are never stored or sent anywhere.

About the Random Token Generator

Tokens and API keys are long random strings used to identify or authorise requests. The more random and longer they are, the harder they are to guess.

This generator creates them using your browser's secure random number generator, in hex, base62, base64url or alphanumeric formats, with your own length, count and optional prefix.

Nothing is stored or transmitted, so the tokens are yours alone.

Key features

  • Hex, base62, base64url and alphanumeric formats
