How Websites Stay Secure JWT, Hashing, and Encryption Explained

🔒 How Websites Stay Secure | Hashing vs. Encryption Explained (with Demo) 🔐

In this video, I break down how websites keep user data secure using hashing and token-based authentication. We'll walk through a real-life example using a basic login system connected to a PostgreSQL database. Learn why storing plain passwords is a big no-no, how hashing works, and how encryption is different.

✨ Whether you're just getting started with web development or want a refresher on security best practices, this video is for you!
