You can use the Xfinity MyAccount mobile app or using a browser on a laptop/PC go to MyXfinity.com. You should have a login name/password for your account but if you've forgotten it or never used one, you should be able to recover or set one up. If all else fails, call 800-COMCAST or 800-XFINITY and ask for help.
