Random Token / API Key Generator
Generate a cryptographically random token, for use as an API key or secret.
Worth Knowing
Unlike a UUID, which optimizes for uniqueness, an API key or secret must optimize for unpredictability — it has to be generated from a cryptographically secure random source so no one can guess or enumerate valid keys. That distinction is the whole security model: length and true randomness are what make a token resistant to brute force. Treat any generated secret like a password — transmit it only over HTTPS, store it hashed where possible, and rotate it if it ever leaks.
How to Use
- Paste or type your length into the Random Token / API Key Generator above.
- Set any additional options: Character set.
- The output updates instantly and is ready to copy.
