To set the private authentication mode, FaceStation F2 has Extended Auth Mode per user information. 

You can set up a specific authentication mode per user. In addition, you can exclude the device authentication mode

How to set up in BioStar 2 Device SDK

You can use BS2UserSettingEx(http://kb.supremainc.com/bs2sdk/doku.php?id=en:user_management_api#bs2usersettingex) instead of BS2UserSetting for F2.
Basically, BioStar 2 does provide the feature "Include device default authentication mode" but the SDK doesn't have a specific feature but you can make it by manually set all modes in the BS2UserSettingEx to 255(system defined mode) then it would work as the device auth mode. 

FAQ

Question: I want to try to enroll a user with only a card and use the Extended Auth Mode for this user. How can I achieve it in SDK? Could I have the detailed data in the BS2UserFaceExBlob? I want to exclude the device default authentication mode.


Answer:

You should fill the settingExinuserBlobs correctly. Then, you would have the user private mode with CARD ONLY.
