I don't know the script either, but one thing to be aware of if the password is stored in a database: many scripts don't store the literal password, they store a hash of the password.
In years past I've seen MD5 used quite often for passwords, I don't know what's hot now.
You can get an MD5 hash of a desired password with PHP like so:
	Code:
	<?php echo md5('your_password'); ?>
 (Note: I haven't tested the above code.)
