Phase 1.5: Email Verification & WSDC Integration

Status: ✅ COMPLETED Date: 2025-11-13 Duration: ~8 hours

---

Overview

Phase 1.5 implements a complete email verification system with AWS SES, password reset functionality, and WSDC ID integration for dancer registration. This phase enhances user account security and provides a streamlined registration experience for the dance community.

---

Features Implemented

1. Email Verification System (AWS SES)

• Dual Verification Methods:
  • Verification link (token-based)
  • 6-digit PIN code
  • User can choose either method
• Email Templates:
  • Professional HTML templates with gradient design
  • Verification email (link + code)
  • Welcome email (post-verification)
  • Password reset email
• Token Management:
  • Secure token generation (crypto)
  • 24-hour expiry for verification
  • 1-hour expiry for password reset
• Resend Functionality:
  • Users can request new verification emails
  • Prevents spam with proper validation

2. Password Reset Workflow

• Request Reset:
  • Email-based reset request
  • Security: No user enumeration (same response for existing/non-existing emails)
• Reset Flow:
  • Secure token sent via email
  • Token validation with expiry
  • Password strength validation
  • New password hashing with bcrypt

3. WSDC Integration

• Two-Step Registration:
  • Step 1: "Do you have a WSDC ID?" choice
  • Step 2: Registration form (auto-filled if WSDC ID provided)
• WSDC API Proxy:
  • Backend proxy endpoint: GET /api/wsdc/lookup?id=<wsdcId>
  • Fetches dancer data from points.worldsdc.com
  • Auto-fills: first name, last name, WSDC ID
• Security:
  • Input validation (numeric, max 10 digits)
  • Error handling for invalid IDs
  • User-friendly error messages

4. Enhanced Registration

• Password Strength Indicator:
  • Real-time visual feedback
  • Color-coded strength levels (weak/medium/strong)
  • Criteria checklist (length, uppercase, numbers)
• Improved UX:
  • Multi-step registration flow
  • Loading states and error handling
  • Responsive design

5. Verification Banner

• Persistent Reminder:
  • Yellow banner for unverified users
  • Appears on all protected routes
  • Dismissible but persists across sessions
• Quick Actions:
  • "Verify Now" button → verification page
  • "Resend Email" button with loading state
  • Dismiss button (session-only)

Known Issues & Limitations

AWS SES Sandbox

• Issue: In sandbox mode, can only send emails to verified addresses
• Solution: Request production access from AWS or verify test email addresses

Email Delivery

• Issue: Emails may go to spam folder
• Solution:
  • Verify domain with SES
  • Configure SPF, DKIM, DMARC records
  • Use verified sender domain

WSDC API

• Issue: WSDC API is third-party, may be rate-limited or change
• Solution: Implement caching if needed, monitor API availability

Token Cleanup

• Issue: Expired tokens not automatically cleaned from database
• Solution: Add cron job to clean expired tokens (future enhancement)

---

Future Enhancements

Short-term (Phase 2)

• Unit tests for new features
• Integration tests for email workflows
• Email template customization via admin panel

Long-term (Phase 3+)

• SMS verification as alternative
• Social OAuth (Google, Facebook)
• Two-factor authentication (2FA)
• Email preferences (notification settings)
• WSDC data sync (automatic profile updates)

---

Performance Considerations

Email Sending

• Asynchronous email sending (doesn't block registration)
• Error handling (continues even if email fails)
• Logging for debugging email issues

WSDC API Calls

• Frontend loading states
• Timeout handling
• Error recovery (retry option)

Database

• Indexed fields: verification_token, reset_token, wsdc_id
• Unique constraints prevent duplicates

---

Maintenance

Monitoring

• Check AWS SES sending limits and bounce rates
• Monitor email delivery success rates
• Log verification and reset attempts
• Track WSDC API errors

Regular Tasks

• Review and remove expired tokens (manual or automated)
• Update email templates as needed
• Monitor AWS SES costs
