The question is not whether you get advantage, but whether it makes it impossible to break.

I am responding to this comment:

"By far the largest deployed facial authentication system is of course Face ID, which this has zero/zilch/no chance at all of working against."

"zero", "zilch", "no chance" -- suggest overconfidence to me. This is not healthy when discussing any authentication system and especially one based on trained model where we don't exactly understand relation between input and output.

It doesn't have to be impossible, It has to be harder than a complex password.
