How can we use PIN in Linux/GNU?

I must apologise here, I made an asumption that RoHos could be used on Linux, purely because @Rosco was a HUGE advocate of LINUX AND Rohos.

But I just found one of his posts, where he mentions using Rohos for Windows (assuming that is his work computer)

HOWEVER, he also wrote a login script for Linux, so hopefully THAT will suit your needs, The link to the script on GitHub is in the quote below.
Again apologies if I wasted your time
