WordPress 5.0以上版本重置后台密码

By | 2020年2月20日

近期登录我的一个博客站的时候, 发现记录的备份密码错误, 由于我有定期更新密码的习惯, 想来是上次更新过后没有更新密码记录器里面的数值.  百度了几个教程, 大部分是通过CPANEL 重置PHD ADMIN里面的数值, 以前也一直这样操作. 然而这次操作了两次发现仍然不管用, 不管是把使用MD5编译器, 还是使用其他教程里面提到的方法, 全部失效.

无奈之下只能GOOGLE之, 不得不说GOOGLE的专业性强过百度太多, 尝试了GOOGLE的几个办法之后. 用终极大招, 直接通过FTP上传到EMERENCY.PHP的执行文件来修改临时密码, 终于解决! 使用这个方法切记在改掉密码之后要删掉根目录下的EMERENCY.PHP文件, 否则可能被黑客利用修改你的密码!!



    1. 把以下文本内容保存成 emergency.php 文件, 注意后缀必须是.php而不是.php.txt , 然后把该文件上传到根目录跟 wp-config.php在同一目录).
    2. 浏览器里输入http://example.com/emergency.php
    3. 输入管理面账号名 (通常是 admin) 和新密码, 然后点击Update Options. 你会看到生效信息
    4. 删掉 emergency.php from your server when you are done. 切记!!!!
