Navicat Premium 12连接MySQL数据库时会出现Authentication plugin ‘caching_sha2_password’ cannot be loaded的错误，解决方法如下

1. 管理员权限运行命令提示符，登陆MySQL

   mysql -u root -p
   password #登入mysql

2. 修改账户密码加密规则并更新用户密码

   ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘password’ PASSWORD EXPIRE NEVER; #修改加密规则

   ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’; #更新一下用户的密码

3. 刷新权限并重置密码

   FLUSH PRIVILEGES; #刷新权限

再重置下密码：alter user ‘root’@‘localhost’ identified by ‘111111’;

现在再次打开Navicat Premium 12连接MySQL问题数据库就会发现可以连接成功了
