Emergency 是由 villageidiot 开发的一个插件，但现在已经无法使用。使用这个插件时一定要非常小心！

使用紧急密码重置脚本
如果上述其他方案无效，可以尝试紧急密码重置脚本。它不是插件。它是一个PHP脚本。

警告
需要你知道管理员的用户名。
它会更新管理员密码，并发送邮件到管理员的邮箱地址。
如果你没有收到邮件，密码依然会被更改。
使用时不需要登录。如果你能登录，就不需要脚本了。
把它放在你的WordPress安装根目录里。请不要将此上传到您的WordPress插件目录。
完成后出于安全考虑删除脚本。
使用说明
将下面的脚本保存为名为 emergency.php 的文件，链接到你的 WordPress 安装根目录（与包含 wp-config.php 的目录相同）。
在浏览器中打开 http://example.com/emergency.php
按照指示，输入管理员用户名（通常是管理员）和新密码，然后点击“更新选项”。会显示一条信息，说明密码更改。会向博客管理员发送一封包含更改密码信息的邮件。
完成后从服务器上删除emergency.php。不要把它留在服务器上，因为别人可能会用它来更改你的密码。
