ServiceNow Data Flow - Send Current Logged on User to SNOW

I just setup BigFix > ServiceNow Data Flow and I have a couple of questions.

1.) Is it possible to send the Current Logged on User from BigFix to ServiceNow and have it populate the “Assigned To” field in SN?

2.) It appears, multi-factor authentication must be disabled for ServiceNow Data Flow to work properly. Is that accurate?

I found the following in Chapter 2. “Fundamental concepts” of the documentation:

 ServiceNow Service Account Requirements
 The ServiceNow Administrator should have a service account that leverages basic authentication with read 
 and write access to the CMDB tables.
