Welcome to the Roku Community, @Matie!
Thanks for reaching out here. We'd be happy to help you contact the right support for this.
Please note that Roku doesn't manage channel logins or authentication, and many Roku channels are developed and maintained by the channel providers themselves.
In cases like this, we highly recommend directly coordinating this with NFL Support.
We hope you find this information helpful.
Best regards,
Carly
