Are you talking about the mydlink email and password (to access the mydlink apps)? or the camera login info?
I checked the email address you used to register here and no information came up. You will need to contact tech support in your area or go to
https://www.mydlink.com/contactIf you have your account but not the camera's login, just reset the camera (hold paperclip in reset hole for 10 seconds and setup from scratch).
