Is it about user authenticating to Qubes (like unlocking screenlocker),
or user logging into some external service? In the first case, why dom0
would send username/password anywhere? I'd expect rather otherwise -
sys-auth sending some token to dom0 to authenticate.
See here for similar solution:

Yes, this is preferred way, see more details here:
While there is python API (as part of Admin API) which among other
things wrap this, it is an overkill here. It will wrap
subprocess.Popen(...) into a little longer line...

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
