If your application stores passwords in plain text or uses fast hashing algorithms like SHA256, your users are at serious risk.
In this video, I break down common password hashing mistakes and show the correct way to hash and verify passwords using bcrypt in a Node.js + TypeScript backend. I also demonstrate a simple React Native client interacting with the secure authentication endpoints.
We cover:
• Why plain text password storage is dangerous
• Why fast hashes like SHA256 are not safe for passwords
• How bcrypt works (salt + cost factor)
• Secure password hashing during registration
• Proper password verification during login
• Why hashing must happen on the server
This video is part of my Application Security series focused on building secure mobile systems with React Native and Node.js.
Security is not a feature — it’s architecture.
