This isn't "Windows Hello style." This program extracts features from a 2d image instead of doing depth reconstruction first. This makes it easy to fool with a piece of paper.

Also this only handles user authentication unlike on Windows where it can be usedpasskey. disk encryption and for passkeys.

Edit: This program also saves the landmarks of your face into a file in plain text when it gets added.
