Restricted to some devices

How to not allow smart-things to appear on all devices.

After registering and adding our TV to Samsung account, all the smart-things devices are niw accessible via TV, which is great if you live on your own.

The issue is anyone using the TV now can turn off/on these devices 

I would prefer to lock access to smart-things on the TV or remove the app from the TV

Please advise
