Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
Your channels are connected to your account, not your individual devices, so all devices on the same account see the same list of channels on the home page channel grid. To have a different list on the kids' set, it would have to be attached to a different account. If you log into your account on my.roku.com then go to https://my.roku.com/account/pin, you can choose a PIN number and set where it must be used, including parental permissions.
