If you signed up for an account directly within the Apple TV and Roku, and provided your email address during the sign up process, you can access your account and watch Motor Trend (MT) from any other supported device.
While your email address was provided, we still need to finish creating your account. Simply go to the MT supported device you want to watch on, enter your password, and click on the 'forgot password' link. This will send you a way to create a new password that will allow you to take MT anywhere you want to be.
If the password reset is not working for you, please submit a ticket directly to us by clicking this link: Submit A Request
Unfortunately, if you signed up for an account directly through your Apple Device or Roku and did not provide MT with your email address (the email address associated with your Apple or Roku account is not shared with us due to privacy reasons) you will not be able to watch MT on any other device.
