To use the Fire TV you will want to register your device. This is a pretty simple process. For the Fire TV it is the same process to both register, and deregister your device.
To do so:
Select Settings from the Fire TV menu.
Go to My Account.
If your device isn't registered, a Register option displays on this screen. Select Register and enter your Amazon account information when prompted.
If your device is currently registered, the name associated with your account displays in this section. If you select it, you'll then see a Deregister option you can use to connect your Fire TV to a different Amazon account. After you deregister, you'll be prompted to register again by entering your preferred Amazon account information.
