Why can't I sign in with my Facebook Page or Group to Buffer?
First of all, we're very sorry for this sudden change made to the sign in flow. We made the decision to remove the social sign in option for pages and groups after a number of incidents with customer confusion and also the security risk this could lead to. We want to prevent customers belonging to the same group or page on Facebook and other networks to mistakingly sign in to each other's Buffer accounts. We also understand that this can lead to troubles signing in and change how you manage your Buffer account and we can't apologize enough.
