This page will provide a brief overview of the SMS (text message) Two-Factor Authentication (2FA) process. You can also find out how to reset your two-factor authentication and troubleshoot issues.
Binance.US requires that you implement SMS Authentication during sign up, however, it is recommended that you add or change to Google Authentication once sign up is complete. Google Authentication is more secure than SMS Authentication.
