Does anyone know how the app is able to login to facebook automatically? It doesn't show up in ios settings "allow these apps to use your facebook account", and it didn't seem to do the custom app-url-protocol flip-flop over to the main facebook app. Or is it as simple as a shared keychain entry because the app is signed by the same publisher as the main app?
- novum 13y agoAlmost certainly a shared keychain.

- mmasashi 13y agoIt seems you are right. Paper recognized my account even without iOS native Facebook login.
