## 📊 **Email Editability - Best Practices Explained:**

### **❌ Why Email Should NOT Be Editable:**

1. **Security Risk**:
   - Email is the primary identifier
   - Changing it can enable account takeover
   - Requires complex verification flow

2. **OAuth Complications**:
   - Breaks Google OAuth connection
   - User loses access to "Continue with Google"
   - Requires re-linking accounts

3. **Verification Complexity**:
   - Need to verify NEW email
   - Keep OLD email active until verified
   - Send notifications to both emails
   - Add cooldown period

4. **User Confusion**:
   - Login with old email won't work
   - Password reset goes to wrong email
   - Support tickets increase

### **✅ Recommended Approach:**
- **Keep email readonly**
- **If user wants different email**: Create new account
- **Alternative**: Add secondary email for notifications (not for login)

## 🔧 **Backend Requirements:**

### **New Endpoints Needed**:

1. **`GET /api/auth/accounts`** - Check if user has Google OAuth
   ```typescript
   // Returns array of auth accounts
   [{ provider: 'google', ... }]
   ```

2. **`POST /api/users/avatar`** - Upload avatar
   ```typescript
   // Accepts multipart/form-data
   // Field name: 'avatar'
   // Returns updated user with new avatarUrl
   ```

3. **`PUT /api/users/profile`** - Update name (already exists for phone)
   ```typescript
   // Add support for 'name' field
   { name: string }
   ```

4. **`DELETE /api/users/account`** - Delete account
   ```typescript
   // Requires password confirmation
   { password: string }
   // Deletes all user data
   ```

---

## 📝 **Implementation Details:**

### **Google Auth Detection**:
```typescript
const checkGoogleAuth = async () => {
  const response = await axios.get(`${API}/auth/accounts`)
  const hasGoogle = response.data.some(acc => acc.provider === 'google')
  setHasGoogleAuth(hasGoogle)
}
```

### **Avatar Upload**:
```typescript
const handleAvatarUpload = async (event) => {
  const file = event.target.files?.[0]
  
  // Validate type
  if (!file.type.startsWith('image/')) {
    setAvatarError("Please select an image file")
    return
  }
  
  // Validate size (5MB)
  if (file.size > 5 * 1024 * 1024) {
    setAvatarError("Image size must be less than 5MB")
    return
  }
  
  const formData = new FormData()
  formData.append('avatar', file)
  
  await axios.post(`${API}/users/avatar`, formData, {
    headers: { 'Content-Type': 'multipart/form-data' }
  })
  
  window.location.reload()
}
```

### **Name Update**:
```typescript
const handleUpdateName = async () => {
  if (!editedName || editedName.trim().length === 0) {
    setNameError("Name cannot be empty")
    return
  }
  
  await axios.put(`${API}/users/profile`, { name: editedName })
  setNameSuccess("Name updated successfully!")
  setIsEditingName(false)
  window.location.reload()
}
```

### **Account Deletion**:
```typescript
const handleDeleteAccount = async () => {
  if (!deletePassword) {
    setDeleteError("Please enter your password")
    return
  }
  
  await axios.delete(`${API}/users/account`, {
    data: { password: deletePassword }
  })
  
  localStorage.removeItem('token')
  window.location.href = '/auth/login'
}
```
