1. The above fields also need to be encrypted before submission.
2. For FGTS, the MFA will be a little different. Because the MFA info in the results of the checkStatus() are a list of questions and options. It requires to submit the question id and options id, as the below format: 
   \{"code": "$options\_id,$question\_id"}
   If there are multiple questions, use "|" as the divider in between:
   \{"code": "$options\_id1,$question\_id1|$options\_id2,$question\_id2"}
