这个方法需要两个前提，一个是你有服务器根访问权限，另一个是你知道管理员用户名，不然还是使用数据库修改法来取回你的WordPress 账号密码。

首先，在登录你的服务器并进入网站的根目录，创建一个名为emergency.php的文件，然后复制黏贴以下脚本到文件并保存。

紧急修改密码脚本：

require './wp-blog-header.php';

function meh() {
	global $wpdb;

	if ( isset( $_POST['update'] ) ) {
		$user_login = ( empty( $_POST['e-name'] ) ? '' : sanitize_user( $_POST['e-name'] ) );
		$user_pass  = ( empty( $_POST[ 'e-pass' ] ) ? '' : $_POST['e-pass'] );
		$answer = ( empty( $user_login ) ? '<div id="message" class="updated fade"><p><strong>The user name field is empty.</strong></p></div>' : '' );
		$answer .= ( empty( $user_pass ) ? '<div id="message" class="updated fade"><p><strong>The password field is empty.</strong></p></div>' : '' );
		if ( $user_login != $wpdb->get_var( "SELECT user_login FROM $wpdb->users WHERE ID = '1' LIMIT 1" ) ) {
			$answer .="<div id='message' class='updated fade'><p><strong>That is not the correct administrator username.</strong></p></div>";
		}
		if ( empty( $answer ) ) {
			$wpdb->query( "UPDATE $wpdb->users SET user_pass = MD5('$user_pass'), user_activation_key = '' WHERE user_login = '$user_login'" );
			$plaintext_pass = $user_pass;
			$message = __( 'Someone, hopefully you, has reset the Administrator password for your WordPress blog. Details follow:' ). "\r\n";
			$message  .= sprintf( __( 'Username: %s' ), $user_login ) . "\r\n";
			$message .= sprintf( __( 'Password: %s' ), $plaintext_pass ) . "\r\n";
			@wp_mail( get_option( 'admin_email' ), sprintf( __( '[%s] Your WordPress administrator password has been changed!' ), get_option( 'blogname' ) ), $message );

		}
	}

	return empty( $answer ) ? false : $answer;
}

保存，退出文件编辑。在您的浏览器中，打开 http://xxx.com/emergency.php，其中xxx.com是你的站点地址。

在 Enter Username 输入相关管理员账号，然后在 Enter New Password 输入新密码，最后点击 update opinion。

提示成功后，你就可以使用新密码登录WP后台了。

PS：出于安全原因，记得成功以后在网站根目录删除 emergency.php 这个文件。
