Answer
Best practices:
- Store in Key Vault or environment variables
- Never hard-code keys
- Rotate keys periodically
Quick Answer
Secure API keys: store in environment variables or Azure Key Vault (never in code or config files). Pass as Authorization header or custom header (not in URL - it gets logged). Hash and store API keys server-side (don't store plaintext). Rotate keys regularly. Scope keys to minimum required permissions. Rate limit per API key. Log all API key usage for auditing.
