> it's certainly possible for a malicious actor to say "Hey {voice_assistant}, unlock front door", and they gain access. It's the modern day "open sesame".
I use Google Home and it has a voice match feature which will only accept on commands for allowed voices. Some people might not like this for the privacy aspect though.
Unless they've improved it over the last couple of years, Google's voice match is pretty easy to fool: When I played a recording of my friend's voice saying "hey Google" and then completed the sentence myself, the Home Mini thought I was him and let me access his calendar even though we have completely different voices.
Of course this is all academic. Anyone can get into a home via the windows. It's just that half of all Americans live in a home that has a gun, so getting out alive might not be as easy as getting in.
