Admin can configure ServiceNow instance to require users who attempt to log in to the instance using SMS-based OTP. When users attempt to log in to ServiceNow, SMS OTP is sent to the mobile number associated with the sys\_user record. Users can enter the six-digit verification code that it sent to the mobile device and verify their identity. You can configure MFA with SMS using the default Twilio as well.
