My First Full-Stack Project Mistake 😅 | Authentication vs Authorization Explained | Bhangaar App

Описание: This was my very first full-stack web app — originally called Bangaar, now renamed Resold.
I built the entire frontend, backend, and integration alone. But I made a rookie mistake — I forgot to add email verification, and people started signing up using my email 😭

That’s when I learned about two basic security concepts —
🔹 Authentication → Identity (Who you are)
🔹 Authorization → Permission (What you can do)

Later, I used Nodemailer to send OTPs and added a proper email verification system.
Moral of the story — take security seriously from day one 💡
