Trustless Device / Security PIn


So I was setting up my newly purchased Galaxy S8 (I know that it ancient history to most) and came across the PIN set section, it had a spot in there to add a “Trustless Device” to avoid having to enter PIN. I thought, well, my sentinel is right here in my pocket, so when I went to search for Trustless devices to add, it didn’t show up, so my idea is that maybe with a few line of codes, a sentinel could act as my trustless device for all sorts of things, like, walking into my front door. Im sure this has been thought of, but I would like this to be implemented yesterday. Thank you ! <That was sarcasm
