Chromebooks have a similar 'unlock with phone' feature but add that the phone must be unlocked - basically utilizing the biometrics of the phone to unlock the computer regardless of biometric hardware presence. It also uses a pretty tight proximity radius (<0.5 meters I'd guess). But if someone could combine this relay exploit with social engineering to get the target to unlock their phone (like an incoming text/notification), maybe that would get computer access. Perhaps there's a more complex handshake that takes place but if not, seems valuable.
