Just to be sure, are you asking how to safeguard your Shield TV from unauthorized access? If so, I presume you could probably sideload any 3rd party Android security lock app to do this, though I am uncertain if this is even feasible, since apps like these are specifically made for the regular Android OS used by phones and tablets, not for Android TV.How-to?
Would like to lock my nvidia shield. I am logged in to div account.
Thought about theft etc.
How are you thinking?
