What is api key generator

An API key generator creates a cryptographically strong key for use in applications, integrations and services. A good API key must be long and random so that it cannot be guessed or brute-forced. The tool helps developers quickly get a secure key without inventing it by hand.

You can choose the format (hexadecimal, alphanumeric, Base64 URL-safe), the length, the case and an optional prefix in a popular style. The key is generated locally in the browser from a secure random source and is not sent anywhere.

How to use

Choose the format, length, case and prefix, then press the generate button. Copy the ready API key with one click and paste it into your config, or generate a new one.
