There are lots of facial recognition stuff around. Phones have it. Computers have it. Takes an image of your face, checks it against whatever stored scanned image it has, and says okay or not.
But the basic function of that is the computer takes an image. With a camera. With just one camera. Which can only take a 2D image. So there is no 3D image taken of your face.
I don't know what exactly goes on behind the scenes, but clearly it processes the image to recognise some features and extrapolate points, and what have you... but it does this from a 2D image.
Which suggests that if you have a suitably fitting photo, you could use that instead. The image would need to take into account that it is also a 2D image and might need to do some manipulation in order to be demanipulated by the processing computer to meet requirements, but it should be possible.
And certainly recognising any adult, no particular one, would be even easier.
Which has been done!
Not just Death Stranding, but I suspect any realistic photo mode would work. Lara Croft? Aloy? William "B.J." Blazkowicz? Computers do so many pixels these days, other computers thing those are enough pixels.
But how long before any photo could do to unlock specific computers?
