resetting icloud or apple id password
i have an apple id (my icloud address) but can’t remember the password or security questions. When i reset password on Apple ID, an email is sent to the icloud email address which i can't access anyway as i don't have the password (as the password of Apple ID is the same as icloud login. Is there a way I can have the password reset link sent to a nominated mobile number rather than an email address that I cannot access? does anyone know how to solve this?
