And if you don't have access to phpmyadmin or to any other "sql-shell" you can try use this, I didn't test it.
Place it to root of your web installation and run.
Code:
<?php
include("./config.php");
try {
$link = new PDO("mysql:host='DB_ADDR';dbname='DB_NAME'", "'DB_USER'", "'DB_PASS'", array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$link -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT);
} catch (PDOException $e) {
die($e);
}
$link->prepare(" UPDATE `DBNAME`.`DBPREFIX_Users` SET `password` = 'e10adc3949ba59abbe56e057f20f883e' WHERE `DBPREFIX_Users`.`username` = 'YOULOGIN';");
$link->execute();
if ($link->rowCount() > 0) {
echo("Password changed!");
} else {
echo("Something failed!");
}
?>
