What is the secure api key generator?

Integrations need secrets that are genuinely unpredictable — a memorable string is not one. This generator uses the browser's cryptographic random number generator to produce keys of your chosen length and alphabet, with an optional prefix so keys are identifiable in logs. Nothing is transmitted: generation happens entirely on your device.

How to use it

  1. 1Enter your key length.
  2. 2Adjust prefix, character set and how many if they apply — leave them as they are if not.
  3. 3Press Generate. Results update instantly, so you can change a number and compare.
  4. 4Save the result to your account if you want to come back to it later.
