WP Password Generator takes the hassle out of creating new WordPress users by generating random, secure passwords with one click.
When administrators create new users through the WordPress admin interface (wp-admin/user-new.php), they are forced to come up with a password for the new user. The administrator is faced with a choice: use a separate password generator app or waste precious time coming up with a clever password only one person will ever see.
WP Password Generator takes the hassle out of creating new user passwords. Simply click "Generate Password" and your user has a unique, 7-16 character password. The password generator function is also totally pluggable, so you can easily change the way passwords are generated in order to meet your standards.
