I disagree with this being something negative. So, I have some crypto, I fall off the stairs, pass out. Should anyone be able to just point your phone to the face to make a call to someone? Yes.. maybe. Should the same be possible for anyone to access your money (be it crypto or not) while you've passed out? hmm... Let's hope neither of us have an accident of course :P I personally disable face id and fingerprint on all my crypto / tradfi apps. Even change apps if that's not possible.
