# IO.getpass (from ruby core) --- io.getpass(prompt=nil) -> string --- Reads and returns a line without echo back. Prints `prompt` unless it is `nil`. The newline character that terminates the read line is removed from the returned string, see String#chomp!. You must require 'io/console' to use this method.
