Scroll down the page and click the link "Add/Manage sub accounts". Enter your full AT&T username and password into the appropriate fields. Click "Log In".
Click "Create Sub Account". Read the terms and conditions then click "I Agree". Click "Next" to activate the setup wizard.
Navigate to the "Member ID" field and enter the username for the sub account. Select "AT&T.net" as the extension for the username. For example, the username will be formatted as "email@example.com".
Create a password for the sub account followed by entering the contact information for the person that the account will belong to into the appropriate fields. Click "Next".
Select a security question from the drop-down menu and enter the answer to the question in the appropriate field. Click "Next".
