in reply to How do I make password prompts not echo back the user?

The easiest solution, under Unix at least, is to call 'stty' to change the terminal's "echo" attribute. I know of no way to do this under Windows or any non-Unix platform, and there may be a more standardized way of doing this (such as via curses or some Term-based module):
print "login: " my $login = <>; print "Password: " system('/usr/bin/stty', '-echo'); # Disable echoing my $password = <>; system('/usr/bin/stty', 'echo'); # Turn it back on
