由于没有人提出一个很好的理由不执行我的要求，因此我认为我的方法是安全的。因此，为了不让这个问题公开，我决定将代码添加为答案并将其标记为已接受。
因此，我有一个名为Easylife_Simulate以下文件的新扩展名：
app/etc/modules/Easylife_Simulte.xml-声明文件：

app/code/local/Easylife/Simulate/sql/easylife_simulate_setup/install-0.0.1.php -安装脚本-添加新的客户属性：
<?php
$this->addAttribute('customer', 'login_key', array(

$key = $this->getRequest()->getParam('login_key');
if (empty($key)){

而已。它为我工作。就像我在问题中说的那样，缺点是，如果2个管理员同时（大约）同时按下同一位客户的登录按钮，则其中一位将无法登录。但是他可以在几秒钟后重复该过程。
