Hi,

                In my case, I have to connect the target system (client system) via OIC.

                While connecting the target system I have to verify two-factor authentications (REST API).

                Here I have explained our custom two-factor authentication.

                "I have hit the REST API with respective headers which is shared by a client. And the response (JSON value) will come as a challenge. (A Challenge is a random number in an encrypted format generated using the user’s MPIN. The algorithm used to generate challenge is (AES 128 bits)). Using the Challenge (random number) we generated an access token for access the client system.”
