I'm in possession of a Fire-Tv stick and therefore quite satisfied. I mainly use Netflix, but I also have access to my brother's Prime Account. About this I would like to watch prime video on the Fire-Tv stick, but without my login with his access data in the Fire-TV stick. The plan is that I use his access data only for Prime Video, otherwise any app I download via his account.
I tried to download the Prime Video APK for Android and install it on the Fire-Tv Stick, but this installation did not work.
If anyone has an idea how to use Prime Video with my brother's account without logging in with my account on the entire stick, I would be very happy.
As far as I know, there's no way. It's kind of paradox to install something that is already firmly integrated into the system. What would be so bad if you sign up with the account of your brother? As long as you do not buy films and series in his name that should not be a problem.
