If you didn't save the key or lost your Google Authenticator:
Please click: Submit the ticket and provide your account number, name and real-name verification certificate number for our customer service department. Once we confirm, we will remove your Google Auth then you can verify a new one. We recommend you to add the "Key" to your favourites. If you delete the Google Authenticator or lost it, you can copy the key and verify a new Google Authenticator again.
