facebook - Is it okay to configure Parse User with public "get" class-level permission? -

-

i'm in process of designing data model ios application i'm using parse backend (first time using parse)

every user of application has both private data should readable , writable owner of data , public data should readable everyone.

i'm considering keeping publicly readable data stored in parse's built in user object , private data in custom object. there downside this? app uses facebook login exclusively and, thus, when user created authdata field populated "facebook: 12345..." is having accessible security problem?

in scenario user object (my public data) need "get" not "find" permissions, need readable knows objectid. rules out dumping entire user's table.

i've read through documentation , "sensitivity" of each user's authdata wasn't clear. i realize if using traditional username/password scheme problem, facebook login? help/tips appreciated.

edit: printed entire user object console on test client (with another, different user logged in) , authdata wasn't returned. right assume suggested strategy wouldn't problem then? authdata appears "special" field isn't returned if user fetches it.
