FAQ

What is an API key and what is it used for?

An API key is a unique identifier used to authenticate and authorize access to API interfaces. It acts like a digital key, controlling access to API resources and ensuring only authorized applications can use specific services. Common uses include accessing cloud service APIs, payment gateways, map services, and social media APIs.

How to generate a secure API key?

The key to generating secure API keys is using sufficient length (32+ characters recommended), a character set including uppercase + lowercase + numbers + special symbols, and a secure random number generator. This tool runs entirely in your browser, using built-in cryptographic random functions. Generated keys are never transmitted over any network.

Is my API key uploaded to a server?

No. This tool runs entirely in your browser. All key generation happens locally on your device. Generated keys never travel over any network and are never uploaded to any server. You can even use this tool offline with complete privacy.

How long should an API key be?

API key security strength is proportional to length. For general use, 32+ characters is recommended. For high-security scenarios, use 64-128 characters. This tool supports lengths from 8-128 characters, letting you adjust based on your needs.
