API Key Storage Best Practices

Never hardcode API keys in source code. Use environment variables (process.env.API_KEY in Node.js, os.environ['API_KEY'] in Python) and load them from a .env file locally. In production, use a secrets manager like AWS Secrets Manager, HashiCorp Vault, or your platform's built-in secrets store. Add .env to your .gitignore immediately.
