The plugin forces all your WordPress site users to keep a strong password at the time they are changing it from their profile page. It displays and error message if a user enters a weak password. The plugin uses the same algorithm to determine password strength as WordPress.
In a WordPress multisite network, network admin can define required password strength from Network Admin Dashboard -> Settings -> Enforce Strong Passwords. Where as on single site it’s admin has this capability from Dashboard -> Settings -> Enforce Strong Passwords page.
Strong passwords are enforced for all users who have any of a specified array of capabilities. Default list is:
edit_published_posts (view Roles and Capabilities). If the user whose password is being edited holds any of these capabilities, the strong password enforcement will be triggered. You can customize this list using the
slt_fsp_caps_check filter, visit this plugin’s page for more info on its filters.
