+Emacs doesn't record keystrokes when a password is read from the
+minibuffer.  However, when the password prompt is in the terminal, the
+keys you use to type in your password gets recorded.  To prevent this
+from happening, you can use the command @command{eat-send-command},
+it'll read password from the minibuffer and send it.  Since the
+password is read from the minibuffer, it's not recorded.
