Random Token Generator

Generate secure random tokens and API keys with custom length and charset.

Instant 100% in-browser Free

A random token is an unpredictable string used as an API key, session identifier or secret. This generator creates cryptographically secure random tokens with the length and character sets you choose, entirely in your browser.

How to use it

  1. Set the token length.
  2. Choose which characters to include (letters, digits, symbols).
  3. Click Generate.
  4. Copy the token.

About Random Token Generator

Tokens and API keys must be unpredictable, because anything guessable can be brute-forced. The strength comes from using a cryptographic random source over a large character set with sufficient length. This generator uses the browser’s crypto API rather than weak pseudo-randomness, so each token is genuinely secure. Use it to seed API keys, session secrets or test data. Generation is entirely local — the token exists only in your browser until you copy it.

FAQ

Are these tokens cryptographically secure?

Yes. They use the browser’s crypto.getRandomValues source, not Math.random, so they are suitable as secrets.

How long should a token be?

For secrets, 32 characters or more from a large charset gives ample entropy. Longer is stronger.

What makes a token cryptographically secure?

A secure token is generated from a cryptographically strong random source and is long enough that it cannot be guessed or brute-forced. This generator uses the browser's secure random API and lets you choose length and character set for your use case.
