2. Avatar downloads to `apps/api/public/avatars/{userId}.jpg`
3. Avatar URL in database: `/avatars/{userId}.jpg`
4. Accessible at: `http://localhost:3001/avatars/{userId}.jpg`

## 2. Profile Page Redesign with Tabs

### **Current Structure:**
```
Profile Page
├── Account Information Card
├── Password Change Card
└── OTP Security Card (all methods together)
```

### **New Structure:**
```
Profile Page
├── Profile Card (with tabs)
│   ├── Edit Profile Tab
│   │   ├── Avatar Upload
│   │   ├── Name
│   │   ├── Email (readonly)
│   │   └── Phone
│   └── Security Tab
│       ├── Change Password Card
│       │   ├── Current Password
│       │   ├── New Password
│       │   └── Confirm Password
│       └── Two-Factor Authentication Card
│           ├── Phone Number
│           ├── WhatsApp OTP
│           ├── Email OTP
│           └── TOTP
```

### **Implementation Steps:**

#### **A. Add Avatar Upload**

**Backend:**
1. Create upload endpoint: `POST /api/users/avatar`
2. Use `multer` for file upload
3. Save to `/public/avatars/{userId}.jpg`
4. Update user's `avatarUrl`

**Frontend:**
1. Add file input with preview
2. Show current avatar
3. Upload button
4. Loading state

#### **B. Reorganize Profile Page**

**Create Tabs:**
```tsx
<Tabs defaultValue="profile">
  <TabsList>
    <TabsTrigger value="profile">Edit Profile</TabsTrigger>
    <TabsTrigger value="security">Security</TabsTrigger>
  </TabsList>
  
  <TabsContent value="profile">
    {/* Avatar, Name, Email, Phone */}
  </TabsContent>
  
  <TabsContent value="security">
    {/* Password Change + 2FA */}
  </TabsContent>
</Tabs>
```

## 3. Account Deletion

### **Backend Implementation:**

**Endpoint:** `DELETE /api/users/account`

**Steps:**
1. Verify user password
2. Delete related data (transactions, categories, etc.)
3. Delete user account
4. Return success

**Code:**
```typescript
// users.controller.ts
@Delete('account')
async deleteAccount(
  @Req() req: RequestWithUser,
  @Body() body: { password: string }
) {
  return this.users.deleteAccount(req.user.userId, body.password)
}

// users.service.ts
async deleteAccount(userId: string, password: string) {
  // 1. Get user and verify password
  const user = await this.prisma.user.findUnique({
    where: { id: userId },
    select: { passwordHash: true }
  })
  
  if (user?.passwordHash) {
    const isValid = await bcrypt.compare(password, user.passwordHash)
    if (!isValid) {
      throw new UnauthorizedException('Invalid password')
    }
  }
  
  // 2. Delete related data
  await this.prisma.$transaction([
    this.prisma.transaction.deleteMany({ where: { userId } }),
    this.prisma.category.deleteMany({ where: { userId } }),
    this.prisma.authAccount.deleteMany({ where: { userId } }),
    this.prisma.user.delete({ where: { id: userId } })
  ])
  
  return { success: true, message: 'Account deleted successfully' }
}
```

### **Frontend Implementation:**

**Add to Security Tab:**
```tsx
<Card className="border-destructive">
  <CardHeader>
    <CardTitle className="text-destructive">Danger Zone</CardTitle>
    <CardDescription>
      Permanently delete your account and all data
    </CardDescription>
  </CardHeader>
  <CardContent>
    <Button 
      variant="destructive"
      onClick={() => setShowDeleteDialog(true)}
    >
      Delete Account
    </Button>
  </CardContent>
</Card>

{/* Confirmation Dialog */}
<AlertDialog open={showDeleteDialog} onOpenChange={setShowDeleteDialog}>
  <AlertDialogContent>
    <AlertDialogHeader>
      <AlertDialogTitle>Are you absolutely sure?</AlertDialogTitle>
      <AlertDialogDescription>
        This action cannot be undone. This will permanently delete your
        account and remove all your data from our servers.
      </AlertDialogDescription>
    </AlertDialogHeader>
    <div className="space-y-2">
      <Label>Enter your password to confirm</Label>
      <Input
        type="password"
        value={deletePassword}
        onChange={(e) => setDeletePassword(e.target.value)}
      />
    </div>
    <AlertDialogFooter>
      <AlertDialogCancel>Cancel</AlertDialogCancel>
      <AlertDialogAction
        onClick={handleDeleteAccount}
        className="bg-destructive"
      >
        Delete Account
      </AlertDialogAction>
    </AlertDialogFooter>
  </AlertDialogContent>
</AlertDialog>
```

## 4. WhatsApp OTP Resend

### **Backend Implementation:**

**Endpoint:** `POST /api/otp/whatsapp/resend`

**Code:**
```typescript
// otp.controller.ts
@Public()
@Post('whatsapp/resend')
async resendWhatsappOtp(@Body() body: { tempToken: string }) {
  try {
    // Verify temp token
    const payload = this.jwtService.verify(body.tempToken) as {
      temp?: boolean;
      userId?: string;
      sub?: string;
    };

    if (!payload.temp) {
      throw new UnauthorizedException('Invalid token type');
    }

    const userId = payload.userId || payload.sub;

    if (!userId) {
      throw new UnauthorizedException('Invalid token payload');
    }

    // Send WhatsApp OTP (live mode for login)
    return this.otpService.sendWhatsappOtp(userId, 'live');
  } catch {
    throw new UnauthorizedException('Invalid or expired token');
  }
}
```

### **Frontend Implementation:**

**Update OTP Verification Page:**
```tsx
// Add resend handler for WhatsApp
const handleResendWhatsApp = async () => {
  setResendLoading(true)
  setError('')
  
  try {
    await axios.post(`${API_URL}/api/otp/whatsapp/resend`, {
      tempToken
    })
    
    setResendTimer(30)
    setCanResend(false)
    setError('')
  } catch (err) {
    setError('Failed to resend code. Please try again.')
  } finally {
    setResendLoading(false)
  }
}

// Add resend button in WhatsApp tab
<TabsContent value="whatsapp" className="space-y-4">
  {/* ... existing code ... */}
  
  <Button
    type="button"
    variant="outline"
    className="w-full"
    onClick={handleResendWhatsApp}
    disabled={!canResend || resendLoading || loading}
  >
    {resendLoading ? (
      <>
        <RefreshCw className="mr-2 h-4 w-4 animate-spin" />
        Sending...
      </>
    ) : canResend ? (
      <>
        <Smartphone className="mr-2 h-4 w-4" />
        Resend Code
      </>
    ) : (
      <>
        <Smartphone className="mr-2 h-4 w-4" />
        Resend in {resendTimer}s
      </>
    )}
  </Button>
</TabsContent>
```

## 5. Auth Pages Design Restoration

### **Check Git History:**
```bash
# Find commits that modified Login/Register pages
git log --all --full-history -- "apps/web/src/components/pages/Login.tsx"
git log --all --full-history -- "apps/web/src/components/pages/Register.tsx"

# View specific commit
git show <commit-hash>:apps/web/src/components/pages/Login.tsx
```

### **Steps:**
1. Find the preferred design commit
2. Compare with current version
