Frequently Asked Questions
What is an API key?
An API key is a unique identifier used to authenticate requests to an API. It acts as a password that grants access to specific services or resources.
What formats are available?
We support various formats including alphanumeric, hexadecimal, base64, UUID-based, and prefixed keys (like 'sk_live_...' used by services like Stripe).
Are these keys secure?
Yes, keys are generated using cryptographically secure random number generation in your browser. They are not stored or transmitted anywhere.
Can I use these for production?
While these keys are cryptographically random, for production use you should generate keys through your own secure backend systems with proper key management.
What key length should I use?
For API keys, 32-64 characters provides excellent security. Longer keys are more secure but may be harder to manage. 32 characters is a common standard.
