Concern moved here to the Xfinity App help section for assistance.

Hey there, sounds like your Xfinity ID hasn't been set up yet. To create your Xfinity ID, go to https://comca.st/3Eq9RY6 or click Create an Xfinity ID from any sign-in page.
Verify your account by confirming some account details. You can use either your mobile phone number or Social Security number (SSN), then click Continue.
If you choose to verify by text message, enter the mobile phone number associated with your account, then click Continue.
If you choose to verify by SSN, you must enter the last four digits of the account holder's SSN, date of birth and a phone number associated with the account. Then, click Continue.
Once your account has been verified, you'll have the option to enter your existing, personal email address. You'll have 72 hours to click the link sent to your email. If you don't click the link, your non-Comcast address will no longer be valid. However, you can still log in using the Xfinity ID or your https://comca.st/3xRdnYN email address. You can also add an email address to your account from the Settings tab in My Account.
When you're all set, you'll see a confirmation page with different ways to access your account and My Account and mobile applications. By clicking Continue, you'll either be sent back to the page you initially visited, or automatically logged in to My Account.

I have the same problem but I have used xfinity stream for years on previous ipads, itouch, and iphone so I know I have an id.  I have not been able to log into ANY xfinity app on my new iPad Air despite deleting and reinstalling the apps.  I put in my id and password and receive the  five digit code on my iphone but, when I enter it, it brings me back to the log in screen.
