Can’t be logged into email on both computer and phone

We can provide more information about why you're unable to access your email on your computer, Loriob22.

Essentially, this is due to bad actors who are trying to access AT&T email accounts. We're aware that this is happening to other email users, and we're working on a resolution. You can get more information about why this is happening and what we're doing to fix it in our article that discusses the 205 error code.

In the meantime, continue to reset your password when prompted and clear your browser's cache and cookies to remove any stored password information. This has helped some email users avoid the login loop.

If you need assistance with anything else, just let us know.

Thank you for visiting the AT&T Community Forums.

Hey @Loriob22, we're here to help with your email. 

Are you getting any error codes when switching devices? We'll be able to narrow potential issues down with any error codes you're experiencing.

What email application are you using? You may want to check and see if the application you're using is compatible with OAuth, AT&T's open authentication security feature. 

If your application isn't compatible, you'll need to create a 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.

Please let us know the results, we look forward to hearing from you!
