getpass(prompt[, stream]) - Prompt for a password, with echo turned off.
getuser() - Get the user name from the environment or password database.

                 echoing of the password contents while reading.

On Windows, the msvcrt module will be used.

      GetPassWarning: When we were unable to turn echo off on the input.

    Always restores terminal settings before returning.
