A Secondary Account (Sub Account) is an account set up under a primary account. For example, the account owner would have the primary account and their spouse or children could have secondary accounts. Each account will have its own User ID and password(s). The User ID for a secondary account will not appear on the bill. You may have up to 20 sub accounts (up to 10 active at one time) under your primary AT&T account.
