Hi Rebecca,
Thanks for reaching out. Yes, you can still use datalink for ServiceNow even when 2FA is present. ServiceNow, along with other software packages, send data directly to Apptio via Datalink via a service account. Service accounts typically interface with ServiceNow+Datalink via encrypted API keys.
I recommend reading through this article: https://help.apptio.com/en-us/datalink/c-servicenow-dl.htm
Once, you have reviewed the article, file a support ticket to schedule a time with our support team, yourself, your SSO team, and the ServiceNow team.
Thanks,
Joe
