A method of dynamic pre-authentication includes receiving at an access point from one or more content platforms a white-list of internet domains that are to be deemed valid for serving content to a non-authenticated user. Updates to the white list are dynamically received from the one or more content platforms which are each responsible for a particular promotional campaign that features specific content. A request is received at the access point from a non-authenticated user for certain of the specific content, which is allowed such that a domain of the content platform responsible for the certain specific content is accessed by the user.
