function reset_admin_password() {
    $user = get_user_by('login', 'admin'); //將'admin'替換成你的用戶名
    wp_set_password('new_password', $user->ID); //將'new_password'替換成你的新密碼

add_filter('auth_cookie_expiration', 'extend_login_session');
function extend_login_session($seconds) {
    return 2678400; //設(shè)置為31天
