Navicat连接MySQL8.0版本时出现Client does not support authentication protocol requested by server；报错的问题解决办法

Windown系统下遇到 Navicat连接MySQL8.0版本时出现Client does not support authentication protocol requested by server；报错的问题解决办法
原因在于MySQL8.0换了加密插件,而数据库管理客户端还是原来旧版本的加密方式，主要在于安装MySQL8.0过程中的Authentication Method这一配置过程，有了不同的加密方式，所以如果选择强加密（默认应该是这种），就会出现上诉报错问题，那么只要修改一下加密方式为保留旧版本的加密方式就ok了，具体操作如下

第一步：启动mysql；

第二步：输入use mysql;

第三步：ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘输入要修改的密码’;

第四步：FLUSH PRIVILEGES; 刷新权限
