On-demand SMS-based OTP

ESET Secure Authentication supports "On-demand SMS OTPs" for certain systems that support primary authentication against Active Directory and secondary authentication against a RADIUS server. In this scenario, users that have already been authenticated against Active Directory have to type the letters "sms" in the ESA OTP field to receive a One Time Password via SMS.


This feature should only be used when instructed to do so by an official ESET Secure Authentication Integration Guide, as it may allow users to authenticate with only an OTP if used incorrectly.
