Hi @theharv,

I understand your concern. We'll gladly help you sign in to your email!


The best place to start is by troubleshooting your email. Just follow the steps below from our email troubleshooting guide: Email Not Working - Troubleshooting Information from AT&T | AT&T Community Forums (

  • Clear your cache and cookies - the most common fix.

  • Update your browser - many features are only compatible with the latest browser and we recommend updating it.

  • Test signing in to your webmail using another browser.

  • Disable browser tools or add-ons - this varies by device and browser.

  • Disable your firewall - this varies by device and browser.

  • Rebuild your mailbox profile - in some instances, rebuilding the profile fixes some issues. You may lose email doing this.

If you're still unable to sign in on your desktop, you can create a Secure Mail Key: Create a Secure Mail Key - Email Customer Support ( This will keep you from having to use your password each time you sign in, thus helping you avoid this kind of sign-in error. Here are the steps:

  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
  1. 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.
  2. Select OK.
  3. 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.

I hope the above informatipon helps!


Please reachout to us if you still face the issue or have any questions.
