To create a password you can use password generators or you can create a php file edited and upload this to your server.

The file should contatin:-

<?php
// Password to be encrypted
$clearTextPassword = ‘passwordplease’;

// Encrypt password
$password = crypt($clearTextPassword, base64_encode($clearTextPassword));

// Print encrypted password
echo $password;
?>

If you save this file as generatepassword.php you upload and then go to:-

http://www.domainname.co.uk/generatepassword.php

This will show the password you selected.
