You will get the below error when logging in to phpMyAdmin without password even if your actual MySQL account itself is passwordless. This is because phpMyAdmin is normally configured to disable passwordless login due to security reasons.
Login without a password is forbidden by configuration (see AllowNoPassword)
To enable log in to MySQL / MariaDB with no password in phpMyAdmin, you'll need to configure AllowNoPassword option in phpMyAdmin's configuration.
User root by default requires system's administrator privilege to log in.
How to connect to root MySQL account without sudo
$ sudo vi /etc/phpmyadmin/config.inc.php
$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
Remove // at the start of the line if exist to uncomment the option.
Depending on distributions, there could be multiple occurrences of that particular line. Ubuntu for example has the following 2 lines;
if (!empty($dbname)) { // other configuration options $cfg['Servers'][$i]['AllowNoPassword'] = TRUE; // it should be placed before the following line $i++; } // other configuration options $cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
