There is no cost to activate a Roku device, and there are no membership fees for creating an account. Create a Roku account on your smart TV or download the Roku app to your iOS or Android device. Although registering for Roku.com/link on your phone could be easier, both approaches are simple. To watch Roku on your TV, you do not need to provide your credit card account information.
Steps to Activate Roku Using roku.com/link (Computer or Mobile):
Turn on your Roku device by connecting it to the TV.
After choosing your language, connect the Roku to a wired or wireless internet network.
An activation code will show up on your TV screen after setup.
Go to Roku.com/link using a web browser on a computer or mobile device.
Log in to your Roku account or register for a new one if you do not already have one.
Click Submit after entering the activation code precisely as it appears on your TV.
Your Roku device will immediately connect to your account; just wait for confirmation.
You can begin streaming as soon as the Roku home screen loads after it has been activated.
