Fix Recommendation

Configure NixOS to have a package that enforces multifactor authentication installed.

Add the following Nix code to the NixOS Configuration, usually located in /etc/nixos/configuration.nix or /etc/nixos/flake.nix:

environment.systemPackages = [
pkgs.opencryptoki
];

Rebuild and switch to the new NixOS configuration:
$ sudo nixos-rebuild switch

Check Contents

Verify NixOS has the packages required for multifactor authentication installed with the following command:

$ which p11sak

/run/current-system/sw/bin/p11sak

If the "p11sak" program is not found in PATH, this is a finding.
