Change my xfinity ID username to something else

@user_96jlpi 

Please give me a link to the page where I can do this. I have tried your AI agent and it keeps thinking it is a password issue and it is not. I want to change the username from the old one to a new one. That is all. 

Is the one you posted this under the old one, or is it a new one?

In order to change your Xfinity ID Username, it would require creating a new one, and then if you wanted you could delete the old one. Here is some information on how to do so. Please let me know if this helps.
