DUO and barcode scanners

Hi,

We are implementing DUO in several Linux servers. Some of the devices that connect to those servers are barcode scanners which use a script to login to the servers via ssh and then access a application. The plan is to whitelist the barcode scanner users, but I am concerned over the (mandatory?) ChallengeResponseAuthentication parameter set to YES.
Does anyone know if the use of DUO can have an impact on (whitelisted) users which access the servers trough devices using scripts to login by ssh?

Thank you!
