🔐 FastAPI Login + Token Authentication

This project demonstrates how to build a secure login system in FastAPI using JWT (JSON Web Tokens) for authentication.

It’s the same project shown in my YouTube Short — Build Login + Token Auth with FastAPI 🚀 (Watch the full demo there!)

⚡ Features

✅ Register a new user (/auth/register)
✅ Login and get an access token (/auth/login)
✅ Verify the current user (/auth/me)
✅ Password hashing using Passlib
✅ JWT token creation & verification with python-jose
✅ Clean project structure with routers, schemas, and models
