thank you

you can authenticate user on phone ios sdk. way user native "login facebook" flow , application hold of facebook token. take token, pass node backend (together email address of user), , can use passport/nodejs verify token belongs email address. if so, user authenticated , can store token email (and other user related custom data) in node node application use later on , fetch existing user in node application when log in again. rest of authentication can use jwt (json web token), https://www.npmjs.com/package/passport-jwt, secure backend , know user sent request.
