lynx-dev passing the authentication login/password via a file?

[Steven Sakata]

We are using "lynx" on a UNIX box to download files from a secure site.  We
currently pass the login and password using the "-auth" argument.  It works
well.  However, my concern is that while it is running, any user can do a "ps" 
and see the login and password in clear text.  I was wondering if there is
a way to have the login and password in a file, or set in an environment
variable instead of having it used on the command line.

Thank you, Steven.
