Change drupal admin password for 100 sites using drush I've a requirement to change admin password for drupal 7 sites which are over 100 and i would like to do it with drush. I know one method of doing it is updating user table with a shell script listing databases in a queue, but i want to achieve this with drush. Would be great if anyone can put me in some reference if they have any idea.

Cheers,

Swaroop.
