On-demand SMS-based OTP

ESET Secure Authentication On-Prem 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.

note

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