There is actually no login or password required for the organizations listed on Goodshop.com. The email address you use when submitting an application for your cause is not linked to or required as a login. Please refer to the ‘how do I change my information’ FAQ for information on how you can update details for your cause.
Where you see the option to login, this is only for individual user accounts which you can access using your personal email address and password (that do not have to be associated with your cause).
