## 説明

This WordPress plugin randomizes the user_id for the user created on WordPress setup,
removing one potential attack factor from the site.

### How it works

Once activated, the plugin will immediately replace the ID for the default admin
user (with user ID 1). By default, the plugin will use random user IDs between 1
and 4503599627370495 (to ensure compatibility with Javascript code using the user
ID).

All newly created users from that moment will be generated with a random user ID
in the defined range.

### How to customize the range for new user IDs

You can customize the range used by the plugin for the random generated user IDs
by using the WordPress filters dfx_random_user_id_max_id and dfx_random_user_id_min_id.

For example, if you want to have all your user IDs between 1000 and 9999 you can
add the following lines to your theme’s functions.php file:

    ```
    function set_dfx_max_user_id( $default_max_id ) {
        return 9999;
    }
    add_filter( 'dfx_random_user_id_max_id', 'set_dfx_max_user_id' );

    function set_dfx_min_user_id( $default_max_id ) {
        return 1000;
    }
    add_filter( 'dfx_random_user_id_min_id', 'set_dfx_min_user_id' );
    ```

Probably, you’ll want to add these lines to your code before activating the plugin,
so your new random main admin user ID is inside your desired range.

Very useful plugin, but would be much better if setting the desired ID number range
was integrated into plugin as a setting rather than relying on a code snippet.

I love this plugin. It easily solved a couple problems I was grappling with. It 
seems like such a simple concept that I’m pretty surprised more developers haven’t
come up with something similar. Would very much appreciate seeing confirmation that
this plugin is up to date for the latest Wordpress versions.

Well built and does its job. Easy to customize for shorter ID’s (16 digits was too
much for my use, lol). Really a great addition to the WP repo, top-notch, my thanks
to the dev! Saved me a nice chunk of time finishing this project 🙂
