## 🛡️ Two-Factor Authentication (2FA)

### What is 2FA?
Two-Factor Authentication adds an extra layer of security by requiring:
1. Something you know (password)
2. Something you have (phone/authenticator app)

### Setting Up 2FA

#### Step 1: Enable 2FA
1. Go to **Profile** > **Security Settings**
2. Find **"Two-Factor Authentication"**
3. Click **"Enable 2FA"**

#### Step 2: Choose Authentication Method

**Authenticator App (Recommended)**
- Google Authenticator
- Authy
- Microsoft Authenticator
- 1Password

**SMS Text Messages**
- Receive codes via text
- Requires phone number
- Less secure than authenticator apps

#### Step 3: Set Up Authenticator App
1. Download an authenticator app
2. Scan the QR code with your app
3. Enter the 6-digit code from your app
4. Save your backup codes
5. Click **"Enable 2FA"**

#### Step 4: Save Backup Codes
```
Your 2FA Backup Codes
Save these codes in a safe place!

1. 123456
2. 789012
3. 345678
4. 901234
5. 567890

Each code can only be used once.
```

**Important:**
- Store backup codes securely
- Each code works only once
- Use if you lose your phone
- Generate new codes periodically

### Using 2FA Login

#### With 2FA Enabled
1. Enter email and password
2. You'll see the 2FA prompt
3. Open your authenticator app
4. Enter the 6-digit code
5. Click **"Verify"**
