Learn How AT&T Is Making Your Email More Secure With Oauth & Secure Mail Key
AT&T and Yahoo are making your email more secure. The new security implementation, also known as Open Authentication(OAuth), works by encrypting your credentials to better protect them from hackers. During this change, you may have trouble logging into some email applications. Not to worry, there is a solution.
When Will This Happen?
Very soon!.
(You can make the changes now by reviewing our online support page for information and assistance.)
What You Need to Do
If using the web to access your email, there is nothing you need to do as our web experience is already OAuth compatible (check below). If you are already using the OAuth settings within mail you may be directed to re-sign in, and if you are using a non-OAuth compatible application, you will need to upgrade to one of the OAuth compatible apps listed below and select Yahoo as your service provider when you sign in. If you do not remember your password, reset it now.
Or
Create A Secure Mail Key
What is a Secure Mail Key? it is a 16-character one-time password used in email applications in lieu of an OAuth flow. Create your key now.
To verify your Application is compatible or for additional FAQs and information, visit our support page.
Compatible vs. Non-Compatible OAuth Applications
| OAuth Compatible |
Non-OAuth Compatible |
| The applications listed below are OAuth compatible. Note that you are using OAuth only if you selected Yahoo as your provider when you set up your account in the application. |
If you use one of the applications below, you need to upgrade to an OAuth compatible application. |
| · Apple Mail, Outlook Mobile, and the Yahoo Mail app on iPhones and iPads running iOS 9.0 and above · Gmail, Outlook Mobile, and the Yahoo Mail app on Android devices running Lollipop/5.0 or above · Apple Mail on Mac running OS 10.11/El Capitan or above · Windows Mail on PCs running Windows 10 |
· Outlook 2010, 2013, 2016 · Mozilla Thunderbird · Windows Mail on personal computers running Windows 8 or older · Apple Mail/Mac Mail on macOS 10.10/Yosemite or older |

No, that was not accurate.
I finally got ATT on the phone, and after about an hour and multiple departments, we got the account unlocked (no, the error messages did not say the account was locked). NOW the accounts are linked. They were NOT previously. NOW I can login to the email account.
I was NOT using an app. I was attempting to login on through the Yahoo! website. I also was unable to login via my mobile phone through the Yahoo! account. I even tried downloading the Yahoo! app, because a relative said that they had to upgrade that app in order to login.
I logged into the ATT website using a username and password, not my email address.

I have not been able to log into my email account for a while now, very frustrating!! I have changed my password, asked that a temporart be sent by snail mail (never received it) Nothing I do helps ! Keep getting a message that I need to update my email sitting but I can't. People are getting upset with me for not answering email when I never get it. I only use my desk top for email so it has nothing to do with my phone.

I’m having a problem not being able to access my email. So I got a new phone number but still have the old phone (not for long) and when I try to login to my email on my new phone or desktop or wherever (except my old phone) it sends a text message to my old phone asking to verify. When I lose the old phone, how am I supposed to get into my email when i can’t verify it.
I LITERALLY spent 6 hours with them and they have not fixed it. They said maybe in 10 days what they have done will work.

@Paulabbee
Did you set up two-factor authorization (2FA)? It sounds like what you are describing. You must have set it up previously through your myAT&T. So it's up to you to correct it to text your new phone number again through your myAT&T.

I don’t recall setting it up, but maybe awhile back. However, I cannot remove it. Do you know how to remove it? The ATT people do not know I guess since they helped me and it still didn’t take care of it.

Since I haven't set up 2FA with an att account I can't help on how to correct it. But I assume you have to do it through myAT&T. If you try to log in there and it calls your old phone as part of the log in why doesn't it log in? You said you still have the old phone to receive the text message as part of the log in.
