Google 2FA
You need to enable Two-Factor Authentication in [Enable Google 2FA]
You can set Two-Factor Authentication ON / OFF, when you Login or Withdraw the funds in [Account Security]
Two-Factor Troubleshooting Tip
The typical reason for two-factor failures is that the clock on your phone has drifted. We only have a two minute window for 2 FA confirmations so if your clock has drifted beyond that, you will not be able to login. Please make sure your phone is configured so sync your time with the cellular network
Backing up the secret key
The secret key is displayed just below the QR code when you first enable two-factor. You can write this code down and keep it in a safe place. You can also snap a picture of the QR code and print it out and keep in a safe place. You can then enable two-factor from another device using the secret key, should you lose or damage your existing device. If you did not write your secret key down when enabling 2FA, you will need to disable 2FA and write the secret code down when re-enabling 2FA.
Problems with Google Authenticator

If you are using a new phone, you will need to transfer your Google Authenticator to your new phone and manually add each app with the secret key or QR code you initially used to enable it.
