Ben Thompson, who runs Stratechery, one of the OG’s of membership-based sites, announced Passport.
It’s membership control software that, among other things, lets membership sites do single sign-in across apps, including Discourse and Spotify (with paid podcasts on Spotify without paying Spotify a cut).
Something like this on Ghost would be incredibly powerful. (Ben is stubbornly still on WordPress, bless his heart).
I realize SSO isn’t easy but it’s hard to look at Passport and not think that’s the future.
