Two-factor authentication provides an extra layer of security. Since two-factor authentication apps are not tied to your phone number (you'll still need a phone number associated with your CoinZoom account in order to buy or sell digital currency), you will be protected even in the event of an attacker compromising your phone number.
When using Google Authenticator for your 2-step verification codes, you will still be protected even if your password is stolen and your phone number is ported. When using Google Authenticator, the only way to generate 2-step verification codes is by physically accessing your Google Authenticator app.
Please note: 2FA replaces OTP email security measures. When you set up 2FA, you will no longer receive those OTP emails when logging in.
