How exactly are you going to reliably and cross-platform pass the password
to the su command?

I can always grab the password, but I'm not sure how to feed that to any
program (login, su, sudo, etc) in a reliable manner (due to different OS
implementations of the programs).

I hoped the su command is always the same.
I have to enter
"su $user" and in the next line the password.
