Unable to verify account name or password. Offline

I have 2 accounts now that cannot verify account name and password; [email scrubbed] and [email scrubbed]

This is happening on all my devices

My other @swbell.net and @att.net accounts are working.  The setting are are exactly the same except for the passwords which I have confirmed are correct by logging into the web client.

I have:

Cleared password and re entered

Cleared mail cache

Deleted and added account

Nothing is working. Very frustrated since it stopped working with me changing anything. and the setting are identical to the accounts that are working.

Please help!!

Hi there, spchrist. We understand that you are unable to verify your username and password in your email client. We can help you with that.


There have been some security enhancements to our email structure. Let's look at them together.


The first enhancement is called OAuth or what is called Open Authentication. It is a token enhancement for email apps. Using the chart below, you can see the apps that require OAuth.

Device & operating system (OS) Apps and programs that use OAuth
iPhones® & iPads® running iOS 9.0 and above
  • Apple Mail
  • Outlook® Mobile
  • Yahoo!® Mail app
Android devices running Lollipop/5.0 or above
  • GmailTM
  • Outlook® Mobile 
  • Yahoo!® Mail app
Mac computer running OS 10.11/El Capitan or above Apple Mail
PC running Windows 10 Windows® Mail
Email app not listed?
Here’s a quick way to find out if your email app uses OAuth. Start setting up a new email account in your app. Your app may offer you a list of email providers that includes Yahoo. If it does, your email app is OAuth compatible. Be sure to select Yahoo as your provider. You’re all set!


If the app or client that you are using is not on the list, then it uses a Secure Mail Key. What a secure mail key is, it is like a password, but it is longer and it is randomly generated also, unlike your web mail password doesn't expire or need to be changed.


Here is how you create the secure mail key:

  1. Go to Profile and choose Sign-in info.
  2. Select the email account that needs a secure mail key. (You’ll find a menu at the top if you have multiple accounts.) 
  3. Scroll to Secure mail key and select Manage secure mail key.
  4. Choose the email address that you’d like to use, if you have more than one.
  5. Select Add secure mail key and then enter a nickname for the secure mail key to make it easier to recognize.
  6. Choose Create secure mail key.
  7. Select Copy secure mail key to clipboard. Make a note of your secure mail key, so you have it handy if you need to update an email app on several devices.
    • For security purposes, the secure mail key only displays until you select OK
    • If you lose or forget the secure mail key, you can create new secure mail keys.
  8. Select OK.
  9. Go to your preferred email app and replace the existing password with your secure mail key. For an IMAP account, delete the existing password for both the IMAP and SMTP servers and replace them with your secure mail key.

If there is any thing else that you need, or get stuck on any of the steps above, please reach back out to us. Thanks for using the AT&T Community Forums.
