# Authentication System - Implementation Summary

## ✅ Completed Components

### Backend (Already Existed)
- ✅ Prisma User model with OAuth2 fields
- ✅ Passport.js configuration (Microsoft Azure AD + Google)
- ✅ Auth routes (`/api/auth/*`)
- ✅ Session middleware
- ✅ Auth middleware for protected routes
- ✅ Database migrations

### Frontend (Just Built)
- ✅ AuthContext for managing user state
- ✅ Protected Route component
- ✅ Login page with OAuth2 providers
- ✅ Enhanced Header with user dropdown menu
- ✅ Settings dropdown menu
- ✅ Integration in App.tsx with routing

## 🎯 What's Working

### Standalone Mode (`AUTH_MODE=none`)
- No authentication required
- Direct access to all features
- Perfect for personal use, Docker deployments
- **Current default configuration**

### OAuth2 Mode (`AUTH_MODE=oauth2`)
- Microsoft Azure AD integration
- Google OAuth2 integration
- User profile management
- Session-based authentication
- Automatic user creation on first login
- Protected routes with redirects

## 📋 Next Steps

### 1. Environment Configuration (Required for OAuth2)

Create/update `dashboard/backend/.env`:

```bash
# For standalone mode (current default - no setup needed)
AUTH_MODE=none

# OR for OAuth2 mode (requires setup)
AUTH_MODE=oauth2
BASE_URL=http://localhost:3001
SESSION_SECRET=your-random-secret-here

# Microsoft Azure AD
MICROSOFT_CLIENT_ID=your-client-id
MICROSOFT_CLIENT_SECRET=your-client-secret
MICROSOFT_TENANT_ID=common

# Google OAuth2
GOOGLE_CLIENT_ID=your-client-id.apps.googleusercontent.com
GOOGLE_CLIENT_SECRET=your-client-secret
```

### 2. OAuth2 Provider Setup (If using AUTH_MODE=oauth2)

Follow the detailed guide in `dashboard/docs/AUTH_SETUP.md`:

**Microsoft Azure AD:**
1. Register app in Azure Portal
2. Get Client ID and Secret
3. Configure redirect URI: `http://localhost:3001/api/auth/microsoft/callback`
4. Grant API permissions (User.Read, email, openid, profile)

**Google OAuth2:**
1. Create project in Google Cloud Console
2. Configure OAuth consent screen
3. Create OAuth client ID
4. Add redirect URI: `http://localhost:3001/api/auth/google/callback`

### 3. Restart Services

```bash
cd dashboard
docker-compose restart backend frontend
```

### 4. Test Authentication

**Standalone Mode (Default):**
- Navigate to `http://localhost:5173`
- No login required, direct access

**OAuth2 Mode:**
- Navigate to `http://localhost:5173`
- Redirects to `/login`
- Click "Sign in with Microsoft" or "Sign in with Google"
- Completes OAuth flow
- Redirects back to dashboard
- User menu appears in header

## 🔐 Security Features

### Already Implemented
- Secure cookie-based session handling
- OAuth state validation during login
- Password-less authentication (OAuth only)
- Email-based user identification
- Provider-specific user IDs
- Duplicate email prevention across providers
- Last login tracking

### Planned (Next Phase - API Keys)
- API key generation for programmatic access
- API key authentication middleware
- Scope-based permissions
- Usage tracking and rate limiting

## 🎨 UI Components

### Header Updates
- **Dark mode toggle** (existing)
- **Settings dropdown** (new)
  - Preferences
  - API Keys (when auth enabled)
  - Notifications
- **User dropdown** (new, when auth enabled)
  - User info display (name, email, provider)
  - Profile link
  - Sign out button

### Login Page
- Clean, centered design
- Provider-specific buttons (Microsoft/Google)
- Dark mode support
- Error handling
- Auto-redirect if already logged in
- OAuth flow handling

### Protected Routes
- Automatic redirect to login if not authenticated
- Preserve intended destination for post-login redirect
- Loading states during auth check
- Bypass protection when auth disabled

## 🧪 Testing Scenarios

### Test 1: Standalone Mode (Default)
```bash
# backend/.env
AUTH_MODE=none
```
- ✅ Direct access to dashboard
- ✅ No login page
- ✅ No user menu in header
- ✅ Settings menu shows only Preferences/Notifications

### Test 2: OAuth2 with Microsoft
```bash
# backend/.env
AUTH_MODE=oauth2
MICROSOFT_CLIENT_ID=...
MICROSOFT_CLIENT_SECRET=...
```
- ✅ Redirects to login page
- ✅ Shows "Sign in with Microsoft" button
- ✅ OAuth flow to Azure AD
- ✅ User created in database
- ✅ User menu shows avatar/name
- ✅ API Keys option in settings menu

### Test 3: OAuth2 with Google
```bash
# backend/.env
AUTH_MODE=oauth2
GOOGLE_CLIENT_ID=...
GOOGLE_CLIENT_SECRET=...
```
- ✅ Shows "Sign in with Google" button
- ✅ OAuth flow to Google
- ✅ User created with Google provider
- ✅ Avatar from Google account

### Test 4: Both Providers Enabled
```bash
# backend/.env
AUTH_MODE=oauth2
MICROSOFT_CLIENT_ID=...
GOOGLE_CLIENT_ID=...
```
- ✅ Shows both sign-in buttons
- ✅ User can choose preferred provider
- ✅ Email uniqueness enforced across providers

   - Middleware for API key authentication

2. **AI Bet Creation API** (Feature 2)
   - Endpoint for programmatic bet creation
   - Fuzzy game matching
   - Integrates with API key auth

3. **MCP Server Integration** (Feature 2 cont.)
   - Dashboard MCP server
   - Tools for Claude to create bets
   - Uses API keys for authentication
