I have Paramount Plus through Roku. We have a new Fire TV in our RV and if I try to watch the Paramount Plus Ap, it wants me to sign in, of course. But, the only sign in would be my email and my Roku password, it does not recognize that. I did not have to set up a separate password for Paramount Plus because we have subscribed through our Roku subscription, please help!
When you subscribe to premium subscriptions through 3rd party systems like Roku, Amazon, Hulu, etc, your accounts are with that 3rd party acting as an agent for the channel, not with the channel itself. In your case, your Parmount+ account is with Roku, not Fire TV (i.e. Amazon). Although there are a few exceptions, these are typically only viewable via the 3rd party service through which you subscribed. In Roku's case, many are viewed via The Roku Channel.
If you want to view on all platforms supported by that channel you typically must subscribe directly with the channel via its web page then use its dedicated app for each platform, authenticating via the credentials you established with the channel account.
Personally, I subscribe to all my premiums directly with each channel. This keeps my viewing options open.
I can’t sign in either
