Sometimes 3rd party logins get disconnected and will give errors when you try to use them to log in. Please create a support ticket letting us know what the error is that you are receiving (Screen Shots help!) and the email address that is associated with your Photofy account.
We will reset your account to a direct login using your email address and assign a temporary password that will help you log in.
If you already have a direct login, please try the "Forgot Password" link on the sign in page to reset your password. Thank you!
