I remember there is a post about this. Anyway, I made one.

Put this in plugin folder: http://bbpress.pastebin.com/f271761bf , use any filename you like

And this to register-success.php of template:

<?php

global $STP_password;

if ($STP_password)

echo "<p>Your password is: $STP_password</p>";

?>

Activate plugin and test.
