Terrible idea.

First question: How secure is it? I am skeptical. Did you see the story 
about the 10-year old whose face was similar enough to what the neural 
nets concluded his parents look like, that he could unlock either of 
their Apple phones? Be skeptical.

Second question: The idea seems to make access more convenient. But do I 
WANT my retirement savings to be so convenient? Security through 
cumbersomeness is real and has value. Safe deposit boxes are cumbersome 
to access, too: and that is a feature.
