   ✓ classes/TwoFactorAuth.php

📁 Admin Pages:
   ✓ modules/security/two-factor-auth.php    (Setup page)

================================================================================
QUICK START - 3 STEPS
================================================================================

STEP 1: Install Database
-------------------------
Visit: http://localhost/copmadinaarea/install_2fa.php

This will:
- Create 4 database tables
- Add system settings
- Register Security module
- Show detailed installation report

STEP 2: Enable Your Own 2FA
----------------------------
1. Go to Dashboard → Security Settings
2. Choose "Authenticator App" (recommended)
3. Scan QR code with Google Authenticator
4. Enter 6-digit code to verify
5. SAVE YOUR BACKUP CODES! (Print or write down)

STEP 3: Integrate with Login
-----------------------------
Add 2FA check to your login pages:

📄 login.php (Admin Login)
   Add after password verification:
   
   require_once 'classes/TwoFactorAuth.php';
   $twoFA = new TwoFactorAuth('admin');
   $settings = $twoFA->is2FAEnabled($user['id']);
   
   if ($settings && $settings['is_enabled']) {
       $_SESSION['2fa_user_id'] = $user['id'];
       $_SESSION['2fa_user_type'] = 'admin';
       header('Location: verify-2fa.php');
       exit;
   }

📄 members/login.php (Member Login)
   Same code, but use:
   $twoFA = new TwoFactorAuth('member');

================================================================================
SUPPORTED 2FA METHODS
================================================================================

🔐 Primary Method:
   ✓ TOTP (Authenticator App)
     - Google Authenticator
     - Microsoft Authenticator
     - Authy
     - 1Password
     - Most secure option

📧 Backup Methods:
   ✓ Email OTP (6-digit code via email)
   ✓ SMS OTP (6-digit code via SMS)*
   
   *Requires SMS provider integration

🔑 Recovery Method:
   ✓ Backup Codes (10 one-time use codes)

================================================================================
HOW IT WORKS
================================================================================

1. User logs in with username & password
2. If 2FA enabled → Redirect to verify-2fa.php
3. User enters 6-digit code from authenticator app
4. Code verified → Login complete
5. Alternative: Use backup code or request email OTP

================================================================================
FEATURES INCLUDED
================================================================================

✅ Full TOTP implementation (RFC 6238 compliant)
✅ QR code generation for easy setup
✅ Backup codes (10 one-time codes)
✅ Email OTP with configurable expiry
✅ SMS OTP ready (needs provider integration)
✅ Attempt logging for security monitoring
✅ Mobile-responsive verification page
✅ Auto-submit on 6-digit entry
✅ Multiple fallback options
✅ Clean, modern UI with gradients
✅ Admin configuration panel
✅ Support for both admin and member logins

================================================================================
SECURITY FEATURES
================================================================================

🛡️ Protection Against:
   - Brute force attacks (attempt logging)
   - Password theft (requires second factor)
   - Session hijacking (2FA required per session)
   - Unauthorized access (even with correct password)

🔒 Best Practices Implemented:
   - Time-based codes (30-second window)
   - One-time backup codes
   - IP address logging
   - User agent tracking
   - Configurable OTP expiry
   - Secure code generation

================================================================================
TESTING CHECKLIST
================================================================================

After installation:

□ Run install_2fa.php successfully
□ Enable 2FA on test account
□ Scan QR code with authenticator app
□ Verify with code from app
□ Save backup codes
□ Logout completely
□ Login again - should prompt for 2FA
□ Enter code from app - should login
□ Test backup code - should work once only
□ Test email OTP option
□ Test "lost device" scenario

================================================================================
TROUBLESHOOTING
================================================================================

❌ "Invalid verification code"
   → Check device time sync (must be accurate)
   → Try code discrepancy (±30 seconds allowed)
   → Use backup code instead

❌ Can't scan QR code
   → Enter secret key manually in app
   → Key shown below QR code

❌ Lost authenticator device
   → Use backup code
   → Request email OTP on verification page
   → Contact admin to disable 2FA

❌ Email OTP not received
   → Check spam folder
   → Verify EmailService is configured
   → Check email queue processing

================================================================================
CONFIGURATION
================================================================================

System settings (in database):
   - 2fa_enforced_admin: Require 2FA for all admins (0=off, 1=on)
   - 2fa_enforced_member: Require 2FA for all members
   - 2fa_grace_period_days: Days before enforcement
   - 2fa_backup_codes_count: Number of backup codes (default: 10)

================================================================================
SMS PROVIDER INTEGRATION (Optional)
================================================================================

To enable SMS OTP, integrate with Twilio or similar:

1. Sign up for Twilio account
2. Get Account SID and Auth Token
3. Edit classes/TwoFactorAuth.php → sendSMSOTP()
4. Add Twilio SDK: composer require twilio/sdk
5. Test SMS delivery
