Auto Unlock - supported
According to this site:


  If you see “Auto Unlock: Supported,” your Mac meets Auto Unlock hardware requirements. If not, you’re out of luck. As a rule of thumb, Mac models manufactured before 2013 cannot use Auto Unlock.


So it looks like it's telling you the Mac supports Auto Unlock.  I have a 2015 MPB with Auto Unlock turned on and my system report still says 'Supported'.
