How to set up two-factor authentication
Log in and click on the Dashboard tab in the navigation menu. From the drop-down, click on the Settings button.
Go to the Two-Factor Authentication section and toggle the switch to ON so two factor authentication will be required every time there is a login attempt.
Click on the pencil icon next to CODE VIA SMS or CODE VIA VOICE CALL to enable these options, confirm the correct phone number(s) and set one of these as your preferred authentication method, then click on Done.
You may need to complete the two-factor authentication process to save the contact information.
