This module adds the security.duosec attributes, which you can use to
enable simple two-factor authentication for NixOS logins.
The module currently provides PAM and SSH support, although the PAM unix
system configuration isn't automatically dealt with (although the
configuration is automatically built).
Enabling it is as easy as saying:
security.duosec.ssh.enable = true;
security.duosec.ikey = "XXXXXXXX...";
security.duosec.skey = "XXXXXXXX...";
security.duosec.host = "api-XXXXXXX.duosecurity.com";
security.duosec.group = "duosec";
which will enforce two-factor authentication for SSH logins for users in
the 'duosec' group.
This requires uid/gid support in the environment.etc module.

- It now uses JavaScript for configuration (only),
so I had to "convert" config for NetworkManager.
- I tested suspend/restart/(un)mount on KDE/Xfce,
Phreedom tested NetworkManager config conversion.
Sshd *must* use PAM because we depend on it for proper session
management. The original goal of this option (disabling password
logins) can also be implemented by removing pam_auth authentication
from sshd's PAM service.
That is, you can say
security.pam.services.sshd = { options... };
instead of
security.pam.services = [ { name = "sshd"; options... } ];
making it easier to override PAM settings from other modules.
