✅ Created email_validator.py - Business email validation
✅ Created firebase_auth.py - Firebase token verification
✅ Created brevo_service.py - Brevo email service for OTP
✅ Created otp_service.py - OTP generation and verification
✅ Updated auth_routes.py - New endpoints for Firebase and OTP login

✅ Frontend Changes (Completed)

✅ Updated package.json with Firebase SDK
✅ Created config/firebase.js - Firebase configuration
✅ Updated services/auth.js - Firebase and OTP auth functions
✅ Updated contexts/AuthContext.jsx - Firebase and OTP support
✅ Created components/auth/LoginForm.jsx - Login UI with both options
✅ Updated App.jsx - Integrated LoginForm component

🚀 Next Steps (YOU NEED TO DO THESE)

Step 1: Install Dependencies

Backend:

cd backend
pip install -r requirements.txt

Frontend:

cd frontend
npm install

Step 2: Set Up Firebase

Create Firebase Project:
- Go to https://console.firebase.google.com/
- Create a new project or use existing one
Enable Google Authentication:
- In Firebase Console → Authentication → Sign-in method
- Enable "Google" provider
- Set project support email
Get Web App Config:
- Project Settings → Your apps → Add Web app
- Copy the config values
Get Service Account Key:
- Project Settings → Service accounts
- Click "Generate new private key"
- Download the JSON file

Set Frontend Environment Variables: Create frontend/.env:

VITE_FIREBASE_API_KEY=your-api-key-here
VITE_FIREBASE_AUTH_DOMAIN=your-project.firebaseapp.com
VITE_FIREBASE_PROJECT_ID=your-project-id
VITE_FIREBASE_STORAGE_BUCKET=your-project.appspot.com
VITE_FIREBASE_MESSAGING_SENDER_ID=your-sender-id
VITE_FIREBASE_APP_ID=your-app-id
VITE_API_BASE_URL=http://localhost:7860

Set Backend Environment Variables: Option A (JSON file path):

FIREBASE_SERVICE_ACCOUNT_KEY=/path/to/service-account-key.json

Option B (JSON string - recommended for Docker):

FIREBASE_SERVICE_ACCOUNT_JSON='{"type":"service_account","project_id":"...","private_key":"...","client_email":"..."}'

(Copy the entire JSON content from the downloaded file)

Step 3: Set Up Brevo

Create Brevo Account:
- Go to https://www.brevo.com/
- Sign up (free tier: 300 emails/day)
Get API Key:
- Settings → API Keys
- Generate new API key
- Copy the key (starts with xkeysib-)
Verify Sender Email:
- Senders & IP → Senders
- Add sender email (e.g., noreply@yourdomain.com)
- Verify via email

Set Backend Environment Variables:

BREVO_API_KEY=xkeysib-your-api-key-here
BREVO_SENDER_EMAIL=noreply@yourdomain.com
BREVO_SENDER_NAME=EZOFIS AI

Step 4: Set JWT Secret

Generate a secure random key:

# Linux/Mac
openssl rand -hex 32

# Or Python
python -c "import secrets; print(secrets.token_hex(32))"

Set environment variable:

JWT_SECRET_KEY=your-generated-secret-key-here

Step 5: Set Frontend URL

FRONTEND_URL=http://localhost:5173  # Development
# OR
FRONTEND_URL=https://your-domain.com  # Production

Step 6: Database Migration

If you have existing data:

The new schema will be created automatically
Existing extractions table needs user_id column
You may need to assign existing records to a default user

For fresh start (recommended for development):

Delete data/app.db (if exists)
Restart application - tables will be recreated

Step 7: Test the Implementation

Start Backend:

cd backend
uvicorn app.main:app --reload --port 7860

Start Frontend:
```
cd frontend
npm run dev
```
Test Firebase Login:
- Navigate to http://localhost:5173
- Click "Google Sign In" tab
- Sign in with business Google account
- Should redirect to dashboard
Test OTP Login:
- Click "Email / OTP" tab
- Enter business email
- Click "Send OTP"
- Check email for OTP code
- Enter OTP and verify
- Should redirect to dashboard
Test Business Email Validation:
- Try personal Gmail account → Should be blocked
- Try OTP with personal email → Should be blocked

📝 Environment Variables Checklist

Backend (.env or system environment)

FIREBASE_SERVICE_ACCOUNT_JSON or FIREBASE_SERVICE_ACCOUNT_KEY
BREVO_API_KEY
BREVO_SENDER_EMAIL
BREVO_SENDER_NAME
JWT_SECRET_KEY
FRONTEND_URL

Frontend (.env)

VITE_FIREBASE_API_KEY
VITE_FIREBASE_AUTH_DOMAIN
VITE_FIREBASE_PROJECT_ID
VITE_FIREBASE_STORAGE_BUCKET
VITE_FIREBASE_MESSAGING_SENDER_ID
VITE_FIREBASE_APP_ID
VITE_API_BASE_URL

🔒 Security Reminders

✅ Never commit API keys or secrets to git
✅ Use .env files (add to .gitignore)
✅ Business email validation is enforced on both frontend and backend
✅ JWT tokens expire after 7 days
✅ OTP codes expire after 10 minutes
✅ Maximum 5 OTP verification attempts

⚠️ Important Notes

Database Schema Change:
- User model changed from google_id (required) to firebase_uid (optional)
- If you have existing users, you'll need to migrate the data
- For development, deleting data/app.db is the easiest option
Business Email Validation:
- Personal email domains are blocked (Gmail, Yahoo, Outlook, etc.)
- Validation happens on both frontend and backend
- Users must use their work/corporate email addresses
OTP Storage:
- Currently stored in memory (works for single server)
- For production with multiple servers, consider using Redis

🎉 You're All Set!

Once you complete the setup steps above, your application will have:

✅ Firebase Google Sign-in (no OAuth credentials needed!)
✅ Email/OTP authentication via Brevo
✅ Business email validation
✅ User-specific data isolation
✅ Secure JWT token authentication

Good luck! 🚀
