Q:

how to stop authentication required in xampp user

Whenever I'm going to load the phpmyadmin the pop-up will appear..

And this is my config.ini.php file

A:

try following this it may help:
In xampp directory there will be a .htaccess file that contains the instructions for Apache to ask for authorization. You can rename it, or go into the file and comment out the following lines: 
AuthName "xampp user"
AuthType Basic
AuthUserFile /opt/lampp/lib/xampp.users
require valid-user
