Hello, Bruce. If you haven't already signed up for fuboTV, it will show you how to begin your "7-day free trial," as well as a sign-in button. When you click it, it will ask you for the same email address you used to register your Roku device, or you can change it and sign up with a different email address.
So it depends on whether you used your Roku's email address or a different one when you signed up for fuboTV.
