I'm pretty new to Linux btw.
I have a new box on the way and i was going to make it into a Kali Linux box. Is it possible to have a 2 step login to the root user. What i mean by this is you login is as user: Root Password: Admin for example but you will also need to use a CAC card to login in as well. So you would need username password and CAC login to get into Root user.
