Logged into stream app - XFinity

In my app it shows that there are no devices using my Xfinity stream app but there are movies and shows showing that have been watched.. that I didn’t watch. Is there a way to get all devices off including tv devices (Roku Tv, Apple TV). Someone is using my information without permission.
