@dieterschmied I believe OP is talking about the code that links a specific device to a Roku account. Each time you set up a Roku, you'll get a link code. If you factory reset a Roku, or otherwise unlink the device from your account, you'll get a new link code.
You should have used one when you set up your Roku.
