1251 Client does not support authenticasider upgrading Mysotocol requested by ser解决办法

navicat premium连接数据库出现1251错误

报错：1251 Client does not support authenticasider upgrading Mysotocol requested by ser

navicat版本不支持这种格式的密码。
解决办法：

查看用户：

select host,user,plugin,authentication_string from mysql.user;

复制下面文字，cmd进入mysql后，粘贴，修改密码（'root1’重新设置密码），回车即可，这样navicat premium连接数据库成功

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root1';

报错ERROR 1396 (HY000): Operation ALTER USER failed for ‘root’@’%’：则用下面的localhost,

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root1'
