How to change root password to MySQL and PHPMyAdmin
You can change the MySQL root password by logging in to the database directly (MySQL -h your_host -u root) then run
SET PASSWORD FOR [email protected] = PASSWORD(your password’);
PHPMyAdmin should use that password so not quite sure what you mean by “for both”.
Make sure to set the new password into phpmyadmin’s config.inc.php too, at line
$cfg[‘Servers’][$i][‘password’] = ‘yourpassword’;
Otherwise, phpmyadmin may not work, echoing
Access denied for user ‘user’@’localhost’ (using password: YES)
