Instead of making (the app user) admin on every page

— is there a way to to have something provided by Facebook — that the Facebook page owner will click and authorize this page on a given page?

I have 2 Facebook pages I want to publish content…. But, trying to avoid creating my Facebook login as admin on their page.

similar to “login via facebook” or login via twitter” where there is no need to create an admin
Or some of the games/apps that do not require admin access

Is this possible?

thanks,
Jac
