Drush upwd command fails with drush/drush 9.1.0

[phrane]

Description:
Drush upwd USER --password="newpassword" to change password fails.

Expected:
Drush upwd USER --password="newpassword" should result in [success] with changed password.

Actual:
The Drush upwd command fails with notification -
" [Symfony\Component\Console\Exception\RuntimeException]
The "--password" option does not exist. "

Observation:
After downgrading to Drush Commandline Tool 8.1.16 (from 9.1.0) and re-running Drush upwd command, it was successful.

My environment:
Ubuntu 16.04
Composer based Drupal 8.4.4 project

password is now an argument, not an option. see drush help upwd.

Understood... So in Drush 9 this is now:

drush upwd USERNAME PASSWORD

thanks!
