Invite Parent

I used the 'Invite parent' button so that my wife could also access the account I access - that way we can both monitor our children's activities - however the email my wife receive just took her to the default onlinefamily.norton webpage and when she registered it had created a new account and asked for her children's details etc.

 

How can I allow access to 'my' account without giving my wife my username and password?
