The current 10 Samsung Tizen app does not require a login, meaning you do not need to activate the device. 

We have a new app that is being rolled out for TV's 2018 and newer. This new app will fix some known issues on the existing app (including the ability to watch Live TV, and issues with freezing). When this is released and you have updated the app, you will be prompted to activate your TV. 

If you have the latest app and are experiencing issues with activating your TV, please click here for instructions on how to activate. 

If you are still experiencing issues please submit a ticket and send through your Samsung TV model as well as a screenshot of the app version you are using.
