How to connect into DB cluster with PhpMyAdmin ?

I had DB cluster and was successfully connected remotely via new droplet with MySQL 8 installed on there.

root@confidential:~# mysql --version
mysql  Ver 8.0.18 for Linux on x86_64 (MySQL Community Server - GPL)
root@confidential:~# mysql -u doadmin -p -h db-mysql-sgp1-****-do-user-****** -P 25060 -D defaultdb
Enter password:

In this new droplet i’m also installing PhpMyAdmin under PHP 7.3, and adding following configuration into /etc/phpmyadmin/

$cfg['Servers'][$i]['host'] = 'CONFIDENTIAL';
$cfg['Servers'][$i]['user'] = 'USER-CENSOR';
$cfg['Servers'][$i]['password'] = 'PASSWORD';
$cfg['Servers'][$i]['auth_type'] = 'config';

Unfortunately when logeed in using the same user/pass that worked in SSH terminal (as shown above), the PhpMyAdmin shown following errors

MySQL said: Documentation

#2054 - The server requested authentication method unknown to the client
 mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
 mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client
 phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

Well lucky me i was able to figuring out the problem. it’s the additional PhpMyAdmin configuration which cause the problem. After i’m editing the additional configuration became :

$cfg['Servers'][$i]['host'] = 'CONFIDENTIAL';

Without user password auth_type

Also modify the authentication method of the user on my MySQL DB Cluster @see [—-installing-mysql]

I was able to logged in to my DB Cluster via PhpMyAdmin.
