Two-step verification is an authentication method using an authentication application such as Google Authenticator.
If you are unable to log in because you do not know the code for two-step verification, please check the following.
The two-step verification code is displayed on the authentication application. It will not be sent to you by short message or e-mail.
If you are asked to enter the two-step verification code, you have already set up two-step verification in the past. (Most of our customers set up their two-step verification before or after they opened their accounts.) You may not be able to verify your account because you have changed your device model, had your device repaired, or deleted the verification app by mistake.
