2FA stands for two-factor authentication and is an added security feature to help protect your account over and above just using your username and password.  Once you log in to your account with your username and password, NDAX will then ask you for a 6-digit code to enter that is refreshed every 30 seconds to prevent unauthorized access to your account even if your password has been compromised. You’ll need to install Authy

We find that most 2FA related issues are due to the time on your phone being out of sync. There is a two-minute window for 2FA confirmations so if your clock is out of sync beyond that, you will not be able to log in.  Please make sure your phone is configured to sync your time with the cellular network. To make sure that you have the correct time in your Google Authenticator app follow the instructions for your operating system below.
