Can’t enable third party access - no gear icon

Good Morning, @user_myoj14 Thank you for sharing that information. Based on what you've described, it would make sense why you're not seeing the gear icon or the Third-Party Access settings. Because you no longer have an active Xfinity Internet or Voice subscription and are only maintaining a Comcast email account, your profile may be operating under a standalone email status. In that scenario, certain account management features that active customers have access to such as the Third-Party Access Security settings used for email clients like Apple Mail, Outlook, or Thunderbird may not be available.

If that's the case, it would explain:

Why the gear icon is no longer visible in your account portal.
Why you don't see a "Third-Party Access Security" option under Account and Identity settings.
Why you're having difficulty connecting the Comcast email account to your iPhone's Mail app or other third-party email clients.

I completely understand how frustrating that is, especially when the support article directs you to settings that don't appear on your account.

If you are seeing an “Account and Identity” link, you are not on the "connect.xfinity.com" page. Comcast/Xfinity may have deleted your email address and might be redirecting you to some other page, perhaps "www.xfinity.com/support/articles/account-email-information".
