🚪 Universal 2FA Door Chip API

---

Ever wished your app had a digital lock? This API is like a factory for secure digital chips: your users get a new "chip" (token) every time they log in, and only with the right code from their email do your protected endpoints open up.

---

How it works:

1. Register – The user gets their chip:

   POST /register
   {
     "email": "[email protected]",
     "password": "your_password"
   }

2. Login – The system sends a one-time code (key) to their email:

   POST /login
   {
     "email": "[email protected]",
     "password": "your_password"
   }

3. Verify 2FA – Only with the right code can the door open:

   POST /verify-2fa
   {
     "email": "[email protected]",
     "code": 123456
   }

4. Get your token ("chip") – Use it to unlock protected endpoints.
