What is API Key Authentication?
API Key Authentication is a straightforward method of securing APIs by including a unique key in each request. It helps identify the calling application or user.
How secure is API Key Authentication?
While API Keys add a layer of protection, they should be used with HTTPS/TLS to encrypt traffic. For sensitive data, consider implementing more robust methods like OAuth 2.0.
How should I manage and rotate API Keys?
Use a secure vault or key management system to store and rotate keys periodically. Immediately revoke compromised keys to prevent unauthorized access.
Can API Key Authentication be combined with other security mechanisms?
Yes, many developers layer API Key Authentication with rate limiting, IP allowlists, or OAuth-based tokens to strengthen overall security and control access more granularly.
