navicat connection mysql prompt Client does not support authentication protocol requested by server error

After installing mysql, Command Line Login is no problem, but suggested that errors occur in Navicat connection. Mysql version: 8.0.15

 

Command is as follows:

1、use mysql;

2、alter user 'root'@'localhost' identified with mysql_native_password by '********';

3、flush privileges;

 Then reconnect

 

 

In MySQL8.0.4 before execution

SET PASSWORD = PASSWORD ( '[Modify password]');
can change the password, but MySQL8.0.4 started, so that the default is not acceptable. Because before, MySQL password authentication plug-in is "mysql_native_password", but now using the "caching_sha2_password".

　　Because the current database has a lot of tools and links packages do not support "caching_sha2_password", for convenience, I was back to being a "mysql_native_password" authentication plugin.

Change the user password, execute the command in MySQL:

ALTER USER 'root' @ 'localhost ' IDENTIFIED WITH mysql_native_password BY ' new password';
modify password authentication plug-ins, and change the password.
