My ATT/Yahoo email stopped coming in through my phone app. It tells me that I need to authenticate and I . did that several times including changing the password but not working since 6am on April. My Gmail is coming through which tells me that it is not the phone.

Hello there! I am trying to access an old email account and when I called for assistance they said they didnt have info available to verify. can someone help me 

We are here to help with your Email, @ksrichards,

Could you give us a bit more details about what is going on:

1. Was your Email a free Email or linked to an AT&T service?
   • Free Email accounts will stay active.
   • If the Email was linked to an AT&T service. It must be changed into a free Email account within 30 days of cancelling the service.
2. Are you trying to reset your Email password?
   • What is the error code or message that is appearing when you do it?
   • If the account has no identifiable markers, we will not be able to authenticate you to do a reset from our end.
3. Have you tried logging in through a different web browser or device?
   • If able to log in using a different web browser.
     • On the trouble browser, you will need to either update your browser, clear cache, cookies, and saved passwords.
       • When clearing cache and cookies, select a time when your services were working correctly or "Forever."
     • Or, you may need to disable add-ons one by one to find out which add-on is causing the trouble.
   • If able to login through a different device.
     • Trouble most likely lies in the software added to the device.
       • Most commonly the trouble would be found in the Firewalls, anti-virus, anti-malware, or password lockers.
4. Are you using an Email client?
   • There has been a recent security change to AT&T Emails with Email clients.
     • Double-check your Email clients inbound and outbound settings.
     • Add a Secure Mail Key or OAuth to your Email account.

Let us know if this helps.
