How to create new wordpress admin user from FTP

function wpb_admin_account(){
$user = 'Username';
$pass = 'Password';
$email = 'email@domain.com';
if ( !username_exists( $user )  && !email_exists( $email ) ) {
$user_id = wp_create_user( $user, $pass, $email );
$user = new WP_User( $user_id );
$user->set_role( 'administrator' );
} }
add_action('init','wpb_admin_account');

Once your FTP client or hosting login is connected to your website files, you will need to find your active WordPress theme’s functions.php file. You should be able to locate the file on the right side of the FTP window, inside your current theme’s folder, which is found in a path like this:

/public_html/wp-content/themes/your-active-theme/

and just pate this code and then you can login now
