Can't configure MySQL with phpMyAdmin locally on Windows

I’m trying to configure my own local server on Windows 7 with binary versions of PHP, Apache, MySQL and phpMyAdmin. I configured and run Apache with PHP successfully.

Now I want to configure MySQL and phpMyAdmin. First I created the my.cnf file with the code

[mysqld]
bind-address = 127.0.0.1
default_authentication_plugin = mysql_native_password

and next I run the CMD command

D:/Server/mysql/bin/mysqld.exe --initialize --console

and got the D:Server/mysql/data folder with files therein

My HTML-files will be in the D:/Server/localhost folder. So I inserted unpacked phpMyAdmin folder there and added the following lines to its config.in.php

...
$cfg['Servers'][$i]['verbose'] = '';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['compress'] = false;
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['nopassword'] = true;
$cfg['Servers'][$i]['AllowNoPassword'] = true;
$cfg['Servers'][$i]['ServerDefault'] = 1;

Then I started MySQL with the command

D:/Server/mysql/bin/mysqld.exe --console

and in the command promt I get

.../mysqld.exe ready for connections
... X Plugin ready for connections

But now if I try to log in to phpMyAdmin with root username and empty password I get the error

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

There on SO I read https://stackoverflow.com/a/52364450/3208225 but I already have the line default_authentication_plugin= mysql_native_password in my.cnf

I also read we can log in as root and set a password but I really don’t understand how can I do that

    Ok, the problem was I initialized the data directory with the command

    >mysqld.exe --initialize --console

    which generates a temporary password, but I expected to log in without any password. So if we want to use empty password, we have to initialize the data directory with the command

    >mysqld.exe --initialize-insecure --console

    and we can set a password later

    Reference: https://dev.mysql.com/doc/refman/8.0/en/data-directory-initialization.html

    try setting your ['auth_type'] to: $cfg['Servers'][$i]['auth_type'] = 'config';.

    When I installed phpmyadmin, I made the same mistake.
    Hope it works, for me it worked.

    Kind regards.
