Export the password

The developer has supplied a hook you can use: called ‘pp_eu_exclude_data’

For example, to include the user_pass field you could add the following to your child theme functions.php. The priority of 20 makes it run after the default filter in the plugin which defines exclusions for both user_pass and user_activation_key.

add_filter ('pp_eu_exclude_data',
   function($exclusions) { return array( 'user_activation_key' ); },
   20);

This assumes you have at least PHP 5.3+

Since you seem to be knowledgeable about this plugin, perhaps you could tell me where to find the .csv file of all the users?
