CRITICAL SECURITY FIXES: • Fix information disclosure in error messages - prevent system info leakage • Implement rate limiting - 5 login attempts/min, 3 registration/min, 3 password reset/5min • Add backend password strength validation - enforce strong passwords with complexity rules • Implement email verification - require email confirmation for new accounts SECURITY ENHANCEMENTS: • Sanitize all error messages to prevent information leakage • Add comprehensive rate limiting with django-ratelimit • Enforce password requirements: 8+ chars, upper/lower case, numbers, special chars • Block common weak passwords (password, 123456, etc.) • Email verification with 24-hour secure UUID tokens • Prevent login without email verification • Security logging for monitoring and audit trails TECHNICAL IMPROVEMENTS: • Add EmailVerificationToken model with auto-expiration • Add password strength validation function with detailed rules • Add send_verification_email() utility function • Add resend verification functionality with rate limiting • Update existing users to verified status for continuity • Add comprehensive URL routing for verification flows BUSINESS BENEFITS: • Enhanced platform security and user trust • Reduced fake accounts and email abuse • Better compliance with security standards • Improved user account protection Security rating improved significantly ⬆️ All critical authentication vulnerabilities resolved ✅ 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
