How do I activate Amazon Prime Video on my device?

To activate Amazon Prime Video on a device, one needs to install the Amazon Prime Video app from the device's app store if it isn't already pre-installed. Upon opening the app, select "Sign In" and enter your Amazon account credentials. If prompted, you'll receive a code that you must enter on a separate web browser. Go to amazon.com/mytv or the specific URL provided by your device's app, sign in to your Amazon account if necessary, and then enter the activation code displayed on your device. Once submitted, your device will be registered and you can start streaming content from Amazon Prime Video right away.
