How to know if your user ID and email share a password
You need to be signed in to myAT&T with your User ID to complete these steps.
Go to Profile > Sign-in information.
In the My linked accounts section, if email, internet, or AT&T U-verse TV is listed, your AT&T email address is associated with your user ID. This means your email and ID share a password.

Free AT&T email
Free AT&T email customers who have paid AT&T services may also have a user ID used for signing in at att.com.
Free AT&T email may include the following domains: @att.net, @bellsouth.net, @ameritech.net, @flash.net, @nvbell.net, @pacbell.net, @prodigy.net, @sbcglobal.net, @snet.net, @swbell.net, or @wans.net.
If you add your AT&T email address to your user ID, they will share the same password.
How do you know if it’s been added? Sign in to att.com with your AT&T email address. If you can see your billing details, your user ID and email are linked and share a password.
U-verse TV or AT&T Internet
U-verse TV and Internet customers have a Member ID (ex. janesmith@att.net) that is both an email address at att.net and a sign-in ID at att.com.
You can use the same ID and password to check your email on att.net and manage your account on att.com.
U-verse TV or AT&T Internet with other AT&T accounts
AT&T U-verse TV and Internet customers have an AT&T email (ex. janesmith@att.net) that is both an email address on att.net and a sign-in ID on att.com.
AT&T U-verse TV and Internet customers who have another AT&T account, like wireless, may also have a user ID (ex. Jane123) that is used for managing that account on att.com.
If the user ID for your other account also manages your AT&T TV or Internet account, your AT&T email and user ID will share the same password. This includes your AT&T email address you use on att.net.
DSL
DSL customers have an AT&T email (ex. janesmith@att.net) that is used on att.net.
Home phone customers have a user ID (ex. Jane123) used for signing in to att.com to manage their account.
If you link your DSL AT&T email to the user ID for your home phone account, the DSL email and the user ID will share the same password.
