Data sharing options

**🐣 Is your feature request related to a problem? Please describe.**

Sharing stats data to other user/client which have their site in my Ackee setup can be done with credentials only.
Of course we can extend Ackee using permanent token, but eh. Finishing project with bunch of revisions from client just made me so damn 'happy' :). And I don't want to touch the code anymore. especially their admin dashboard

**💡 Describe the solution you'd like**

Which can be SUPER helpful if Ackee provide something like unique url for every target domain and then have some option to access the page without main admin credential. Something like simple access code/pin stored in db, or even just the unique url with option to make it publicly available.
Of course Ackee need to be as lightweight as possible. This solution no need to add multiple user support for ackee, The only additional record in my mind is like a key named public or private with boolean value. Access code, and some frontend route logic. No additional endpoint, no data separation. Just add additional way for data serving. I didn't think this solution will made Ackee more heavy.
