# Two-Factor Authentication (2FA)

Secure your account with two-factor authentication for enhanced protection.

## What is 2FA?

Two-factor authentication adds an extra layer of security by requiring:
1. Something you know (your password)
2. Something you have (your phone or authenticator app)

## Setting Up 2FA

### Method 1: Authenticator App (Recommended)
1. Go to **Account Settings** > **Security**
2. Click **"Enable 2FA"**
3. Choose **"Authenticator App"**
4. Scan the QR code with Google Authenticator, Authy, or similar app
5. Enter the 6-digit code to verify
6. Save backup codes in a secure location

### Method 2: SMS/Text Message
1. Go to **Account Settings** > **Security**
2. Click **"Enable 2FA"**
3. Choose **"SMS"**
4. Enter your phone number
5. Enter the verification code sent to your phone
6. Save backup codes

## Using 2FA at Login

After enabling 2FA, you will:
1. Enter your email and password
2. Enter the 6-digit code from your authenticator app or SMS
3. Click **"Verify"** to access your account

## Backup Codes

- Generated when you set up 2FA
- Use these if you lose access to your 2FA device
- Each code can only be used once
- Store them securely (not on your phone)

## Disabling 2FA

1. Go to **Account Settings** > **Security**
2. Click **"Disable 2FA"**
3. Confirm with your password
4. Note: This reduces your account security
