PHPMyAdmin is giving me a message saying that the user (root) does not have a password.
So, how can I create one?
On linux (debian 9) after resetting the mysql(Maria DB) root password, you just have to edit the phpmyadmin db config file located at /etc/phpmyadmin/config-db.php
gedit /etc/phpmyadmin/config-db.php (as root)
