Thanks, but I'm really only looking for some kind of "'su -c'-credential

I'm using gpg-agent eversince which handles my ssh-keys perfectly.  But
of course I'm not logging in as SuperUser, just regular user with

So I'm logged in by pub-key-auth with passphrase from gpg-agent as
regular user – convinient so far.

But now I have to re-type the SuperUser password any time I utilize 'su

On MacOS, I just have to do SuperUser privilege authorization once, then
sudo doesn't ask on subsequent call.
That's what I'm looking for :-)
