Well, I would try to use the Terminal interface of the Unix library :

open Unix

let read_pass () =
  let attr = tcgetattr stdin in
  tcsetattr stdin TCSAFLUSH { attr with c_echo = false };
  let line = read_line () in
  tcsetattr stdin TCSAFLUSH attr;
  line

It work. Of course you could do something to print * when the user
type something, but this is a first solution. By the way i don't know
if this work on windows.
