API Security Reminder

APIs are the backbone of most applications, and security should be a top priority.

  1. Always use authentication (JWT, OAuth, API keys).
  2. Restrict CORS to trusted origins.
  3. Implement rate limiting to prevent abuse.
  4. Avoid sensitive data exposure in API responses.

Security isn’t something to “add later” — it must be built-in from day one.
