+---
+
+## New API Endpoints
+
+### Email Verification (Stub)
+
+| Endpoint | Method | Auth Required | Description |
+|----------|--------|---------------|-------------|
+| `/api/auth/verify/status` | GET | ✅ Yes | Get email verification status |
+| `/api/auth/verify/send` | POST | ✅ Yes | Send verification email (stub) |
+| `/api/auth/verify/email` | POST | ❌ No | Verify email with token |
+| `/api/auth/verify/resend` | POST | ✅ Yes | Resend verification email (stub) |
+
+### Account Settings
+
+| Endpoint | Method | Auth Required | Description |
+|----------|--------|---------------|-------------|
+| `/api/users/me/settings` | GET | ✅ Yes | Get account settings |
+| `/api/users/me/settings` | PUT | ✅ Yes | Update account settings |
+| `/api/users/me/change-password` | POST | ✅ Yes | Change password |
+
+---
+
+## Features
+
+### Email Verification (Stub Implementation)
+
+```bash
+# Get verification status
+GET /api/auth/verify/status
+Authorization: Bearer <token>
+
+Response:
+{
+  "email_verified": false,
+  "message": "Email is not verified"
+}
+
+# Send verification email (stub)
+POST /api/auth/verify/send
+Authorization: Bearer <token>
+
+Response:
+{
+  "message": "Verification email sent (STUB - no actual email sent)",
+  "email_sent": true,
+  "verification_token": "abc123..."  // For testing
+}
+
+# Verify email with token
+POST /api/auth/verify/email
+Content-Type: application/json
+
+{
+  "token": "abc123..."
+}
+
+Response:
+{
+  "message": "Email verified successfully",
+  "email_verified": true
+}
+```
+
+**Note**: This is a stub implementation. In production:
+- Use an actual email service (SendGrid, AWS SES, etc.)
+- Send HTML emails with verification links
+- Store tokens securely
+- Implement rate limiting
+- Add email expiry checks
+
+### Account Settings
+
+```bash
+# Get settings
+GET /api/users/me/settings
+Authorization: Bearer <token>
+
+Response:
+{
+  "email": "user@example.com",
+  "username": "username",
+  "email_verified": true,
+  "recovery_enabled": true,
+  "email_notifications": true,
+  "theme": "light",
+  "language": "en",
+  "timezone": "UTC"
+}
+
+# Update settings
+PUT /api/users/me/settings
+Authorization: Bearer <token>
+Content-Type: application/json
+
+{
+  "email_notifications": false,
+  "theme": "dark",
+  "language": "es",
+  "timezone": "America/Argentina/Buenos_Aires"
+}
+
+# Change password
+POST /api/users/me/change-password
+Authorization: Bearer <token>
+Content-Type: application/json
+
+{
+  "current_password": "CurrentPassword123!",
+  "new_password": "NewPassword456!"
+}
+
+Response:
+{
+  "message": "Password changed successfully. Please login again."
+}
+```
+
+**Security Features**:
+- Current password required for password change
+- All tokens invalidated on password change
+- Token version incremented automatically
+- User must re-login after password change
+
+---
+
