If your mobile app exposes a login endpoint without rate limiting, it is vulnerable to brute-force and credential stuffing attacks.
In this video, I demonstrate how to implement secure rate limiting in a Node.js + Express backend using TypeScript, and how to properly handle 429 responses in a React Native client.
We cover:
• Why login endpoints are high-risk
• How brute-force attacks work
• Implementing route-level rate limiting
• Handling HTTP 429 (Too Many Requests)
• Improving UX while maintaining security
• Production considerations (Redis, distributed systems, reverse proxies)
This video is part of my Application Security series, focused on building secure mobile systems with React Native and Node.js.
Security is not just about authentication — it’s about protecting your infrastructure from abuse.
