Create a AT&T
secure mail key.
AT&T calls it a secure mail key rather than an app password. Any mail app that doesn't sign in through AT&T's own login screen needs one — your AT&T password on its own will be rejected.
Applies to att.net, sbcglobal.net, bellsouth.net, ameritech.net, pacbell.net, swbell.net, prodigy.net addresses.
Step by step
How to create your secure mail key.
- Go to your AT&T account profile and sign in with your AT&T ID and password.
- Choose Settings, and confirm the account you're updating (use Switch if it's the wrong one).
- Select Add secure mail key, give it a nickname, then select Create.
- Copy the 16-character key.
- In your mail app, replace the password with the secure mail key — on both the incoming and outgoing server, if it asks separately.
Worth knowing
- Secure mail keys never expire, and changing your AT&T password does not invalidate them.
- Create one key per device, so you can revoke a single device without disrupting the others.
- If your account is ever locked, AT&T deletes all existing keys and you'll need to create new ones.
- Aliases and disposable addresses don't need their own key.
