Hi pscla
Welcome to the Roku Community!
TV Everywhere channels require that you authenticate with your cable or satellite provider to verify that you are eligible, for example, that you subscribe to Showtime to access the content in Showtime Anytime. After you add the channel to your Roku device, launch the channel and follow the on-screen instructions.
- Note: To authenticate, you will need the login credentials (username and password) for the account you created with your cable or satellite provider. If you do not have an account or have forgotten your credentials, you will need to contact your service provider.
Let us know what you find out so that we can assist you.
Best regards,
Arvy
