Have you tried

(add-hook 'comint-output-filter-functions 'comint-watch-for-password-prompt)

This is documented in the info node for shell mode, as is the command
send-invisible.

Note that even if you use this to stop Emacs echoing your password as you
type, the last 100 keys you pressed will still be visible with M-x
view-lossage, C-h l. If you want to be paranoid (and of course you do,
right?) get in the habit of pressing 100 keys (eg arrow keys) after
entering a password.
