Navicate连接MySQL出现2059-Authentication plugin 'caching_sha2_password' cannot be loaded:的解决方案

使用Navicate Premium12.0 连接MySql8.0出现2059-Authentication plugin 'caching_sha2_password' cannot be loaded:的错误，解决方法如下

 1、打开MySQL 8.0 Command Line Client工具登陆到MySQL

2. 修改账户密码加密规则并更新用户密码

 ALTER USER '登录名''@'localhost' IDENTIFIED BY '密码' PASSWORD EXPIRE NEVER;#修改加密规则  

 ALTER USER '登录名'@'localhost' IDENTIFIED WITH mysql_native_password BY '密码';   #更新一下用户的密码 

注意：如果提示 Operation ALTER USER failed for '登录名''@'localhost' 

直接把localhost换成%即可

3. 刷新权限并重置密码

FLUSH PRIVILEGES;   #刷新权限

再重置下密码：alter user '登录名t'@'localhost' identified by '密码';

重新连接即可
