It is highly recommended that you use a username and password combination that is secure and easy to rememnber.  Here is a decent resource to get you started...  I agree with the pass-phrase, password safe and blackbook approaches mentioned in the comments of this article.

It is also recommended that you take advantage of the Password Hint feature available in version 1.2.1.7 or greater.  This will allow you to display a password hint on the screen if you forget your password.

 

As a last resort, we have a tumbling password available for you to use to reset your password.  Just open a ticket and send us your username.  We will send back a reset password that will allow you to change your password.  The reset password will expire at the end of the day it was supplied.
