Answer
Use environment variables, encrypted config files, or framework vaults. Never store secrets in code or public repos.
Quick Answer
Store secrets in environment variables, not in code. Use .env files (loaded by dotenv library) for local dev. Never commit .env to version control. In production, use server environment variables, secrets managers (AWS Secrets Manager, Vault), or encrypted config files. Access via getenv() or ENV superglobal. Separate config per environment (dev, staging, production).
