Double Authentication
Todos eCode Double Authentication (DA) is a development for enhancing the function of a One Time Password (OTP)1 generating device that can not accept a challenge in a Challenge/Response2 scheme (i.e. Printed OTP or ezToken without PIN-pad).
By displaying a prefix to the next OTP on the web page, the end user is given a protective tool – simple to understand – for not giving away any secret before he or she is assured that the current connection is with the correct bank system.
