Now you can force your site users with executive capabilities to use something strong while updating their passwords.
Force Strong Passwords plugin easily does this for you. WordPress user profile includes a JavaScript-powered indicator as a guide to the strength of a password being entered. However, there is nothing to stop users entering weak passwords.
What this plugin does is it duplicates the WordPress JavaScript password strength check in PHP, and forces users with executive powers to use a strong password.
Hence user having capability to publish posts, upload files, make editing to published posts must have a strong password. All you need is install and activate it. That’s all.
