Proxy authentication

Hi.  I am trying to use Guix at my workplace, where we have mandatory
proxy.  In my foreign distribution (Debian 9), I have configured Gnome
for automatic proxy configuration (PAC file) and, for applications that
do not integrate with Gnome’s proxy configuration (such as Emacs), I
have set up ntlmaps (localhost:5865).  I have tried to make Guix use
ntlmaps, but guix pull fails with hash mismatches.  For example:
--8<---------------cut here---------------start------------->8---
Starting download of 
/gnu/store/zdahqsfvra1r2ic61x1blh3i3p7xsax6-libpng-1.6.29.tar.xz
From 
http://downloads.sourceforge.net/project/libpng/libpng16/1.6.29/libpng-1.6.29.tar.xz...
following redirection to `https://sourceforge.net/projects/libpng/files/'...
warning: 'https_proxy' is ignored

sha256 hash mismatch for output path 
`/gnu/store/zdahqsfvra1r2ic61x1blh3i3p7xsax6-libpng-1.6.29.tar.xz'
  expected: 0fgjqp7x6jynacmqh6dj72cn6nnf6yxjfqqqfsxrx0pyx22bcia2
  actual:   1kwj40d23c25r9q67vk9giqrq7vp4zsrxvrzxm45zpy01nbhnxpa
--8<---------------cut here---------------end--------------->8---

Now I want to make Guix talk to the corporate proxy server directly (not
mediated by ntlmaps) but then it needs to authenticate.  I could
temporarily put my login and password in the proxy URL in
/etc/systemd/system/guix-daemon.service.d/override.conf, and erase it
after using Guix.  I am afraid, though, that these environment variables
could be logged.  So, is it secure to temporarily put proxy login and
password in override.conf, or could they be inadvertently logged?
