Score-based authentication

In addition to the OTPClosed A password that is valid for only one authentication process. OTPs can be used only once, and each authentication process requires a new OTP., the Digipass response based on a challenge or the e-signature generation, the Digipass SDK can generate a Digipass response which includes scoring information from the hosting platform.

The principle of a score-based response is to send information about the status of the hosting platform or the context of the Digipass SDK usage to the authentication server through a Digipass response.
