Look in the config file normally located in the root of the folder phpBB is in. The information is in plain text. ie: config.php

// phpBB 2.x auto-generated config file
// Do not change anything in this file!

$dbms = 'mysql';

$dbhost = 'localhost';
$dbname = 'yourBBuname';
$dbuser = 'userNameHere';
$dbpasswd = 'passw0rdhere!';

$table_prefix = 'phpbb_';

If you change it in the config file you will need to change it in mySQL. Your system administrator can assist with changing in mySQL or if you have phpMyAdmin installed for web-based access the option is within there.
