User ID or password

Update your user ID if it’s something easy to guess, or it’s been compromised. 

Change your password if you think someone has accessed your account. Try to create a long password with a mix of uppercase and lowercase letters, numbers, and symbols. If you have more than one ID, be sure to use different passwords for each one. Find out how to change your user ID or password

• Wireless passcodes are used for wireless accounts that aren’t combined with other services like AT&T Internet, Phone, or U-verse^® TV. You can use this to add an extra layer of security to your online account when you turn on extra security.
• Account passcodes are available for AT&T Internet, Phone, and U-verse TV accounts, as well as combined accounts that include wireless service.
