The Importance of API Keys
API keys are unique identifiers used to authenticate requests associated with your project or application. They serve several crucial purposes:
- Authentication: Verifying the identity of the calling application.
- Authorization: Determining if the application has permission to access the requested resource.
- Rate Limiting & Quotas: Tracking usage to enforce limits and prevent abuse.
Best Practices for API Key Security
- Keep them Secret: Treat API keys like passwords. Never embed them directly in client-side code or commit them to public repositories.
- Use Environment Variables: Store API keys in environment variables on your server.
- Principle of Least Privilege: Grant API keys only the permissions they absolutely need.
- Rotate Keys Regularly: Periodically regenerate your API keys to minimize the impact of a compromised key.
- Monitor Usage: Keep an eye on API key usage to detect any suspicious activity.
