All the OTP forge components validate using email integration.
I am creating an application which needs to validate the user's mobile number and email address.
Hi,
I think these discussions may help you get idea about sending sms from mobile app: https://www.outsystems.com/forums/discussion/48244/sending-sms-from-application/

The OTP validation will be same for email and mobile. What different is about send OTP to email or mobile (sms).
