Email Message -
Email Message two-step authentication works by submitting a one-time security PIN sent to the email address of your choosing. This pin is sent upon correctly submitting your account's username and password credentials.
Please enter an email address in the provided field and click the Add Email Message button.
Then enter the pin in the provided field and click the Verify button.
Once two-step authentication has been verified, each subsequent attempt to log-in to your TierraNet account will require both correct username and password credentials, as well as a second authentication method.
