Use both Cameras for sign in.

Windows hello does this too.

Just he possibility that Howdy verifies, that both IR face an camera face is matching.

Perhaps in the future there is also the possibility of a colab with fprint so you can only get in with password or matching face and fingerprint.

Take a look at #608

As for combining with fprint, you can already do that! Because both are just PAM modules you can set both as required for authentication, although that would probably get you in some very frustrating situations
