Random User IDs

外掛說明

這個外掛會將在 WordPress 安裝設定時建立的使用者的 user_id 隨機化，進而移除網站的潛在攻擊因素之一。

外掛運作方式

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.
