Lost your store password?
From Spiffy Stores Knowledge Base
If you've forgotten your password, go to your store's login page which can be found by adding "/admin" to the end of your store's address in your browser. To reset your password, click on the "Lost your password?" link. On the next screen, enter the email address you usually use to log in to your store, and click "retrieve password". Instructions will then be sent to you to reset your password.
