From an admin perspective is there a way to differentiate the users that use "Login with Facebook" feature from other users either from the admin panel (haven't been able to find this) or if not where/how would this information be stored in the db structure? Thanks!
The only table I could see with any Facebook related data is xf_user_external_auth
I believe that is for those members who have associated their Facebook account.
Excellent, thanks Brogan. Looking at the data it would appear that there is one record in that table per user that uses the feature, good info for gauging usage for that feature no doubt though. Thanks!
