I have two Xfinity accounts--one in DC and one in Mass. I can only access the DC account through My Xfinity. How do I add a second account, or set up a second My Xfinity platform?
Start to create a new Xfinity username for your second home account number. On the sign in page toward the bottom it says:
Click on "Create one" and go through the process. When it's ask for your email address type in the same email associated with your previous username and it will ask you if you want to link accounts. Say yes and you're done.
