Pretty much says it all. I see that TMO is texting all their customers urging them to set a passcode as another layer of defense against scammers.
Hello rmnelson, adding a pass code to your account can provide a 3rd layer of protection against theft. You can add a pass code by calling our Xfinity Mobile phone support at 888-936-4968 or by going into an authorized Xfinity Mobile dealer.

I came from TMO where they used the last 4 of the SS # which, with all the data breaches, is probably compromised for everyone and unsuitable for any security purpose. But the CC# is clearly a much better idea, and provides the function that I want. So I will apologize for wasting your time. Thanks again for your help.
You're welcome, have a good day.
