I'm pretty sure you'll be able to block that voice command. Or else my kids will have a field day with it--unlocking stuff.
Have you tried it? I'm going to try it tonight and see what happens.
Does anyone else think Xfinity is crazy to put "What is my WiFi password?" as a voice commands for their remote? Do I really want any random person that comes into my home that has a moment alone with my remote to know my WiFi password? Repair men, cleaning people, visitors? I think this is a security risk. Do I want people to be able to hack my network because my remote helped them, especially in a world that has more & more connected devices?
