Re: If I change my password on my Dish account, will I have to reauthorize all of the Roku channels?
Since I see nobody has responded since you posted yesterday, I'll make a guess.
I'd expect any Roku channel authorizations tied to your Dish account would still keep working until the next time the channel wants to re-verify your credentials. Most cable-type channels do this periodically to re-confirm you still are entitled to stream the channel thanks to your Dish subscription. When you re-confirm, you'll have to do it with your revised Dish password.
But again, this is just a guess.
