In my system, only with―from man emacs―“
             -Q, --quick
                      Similar  to  "-q --no-site-file --no-splash".  Also, avoid processing X re‐
                      sources.
” is the prompt transferred to the minibuffer.

I'll check and tweak the startup configuration.

Thanks!

When I studied at that university, shared machines were a thing. I didn't know if they are still, but I'd also try with:

emacs -q # that's lowercase q

If the problem still happens, it's likely in the site-start.el , and not in .emacs

Yes, that is expected.  The minibuffer prompt should hide your password
with asterisks as you type it.

I think this may not be a bug in Emacs, but a problem somewhere in your
Emacs configuration.  Comment out parts of your .emacs until you find
the culprit.
