Hi @llynch8711

We understand your concern. Let's get the help you need.

We appreciate your efforts in attempting the basic troubleshooting steps.

Since you're able to log in through phone, we'd recommend that you create a secure mail key where you can log in directly without using the password. 

Let us know how it goes!

For further assistance we're here to assist you.

Thank you for contacting AT&T Community Forums,

Maria, AT&T Community Specialist.

While I appreciate your efforts to resolve this, the secure mail key instructions send me to the att.com log-in screen . . . which isn't accessible to me because of the issue I've described above.  Thank you anyway, Maria.

Thanks for writing back to us @llynch8711.

We understand, and we'll point you in the right direction.

We recommend that you fill out the online webform AT&T Yahoo Email account recovery (att.com) with details about your email account and recent mailbox activity. Once submitted, AT&T will attempt to match the information provided against AT&T internal records to validate the email account.

If the account is deemed valid, an AT&T customer care agent will contact you to assist in regaining access to your email account.

Please feel free to reach out to us for further assistance.

Thank you.
David, AT&T Community Specialist.

Thank you for the suggestion.  About 24 hours after this issue started, I was able to access my email again on both my phone and my laptop.  Hmmm . . .
