According to our system requirements 2-factor authentication is not supported in Nebula Synchronizer. However, in Office 365 it is now possible to create an app password when using 2-factor authentication.
An app password is a code that gives an app (like Nebual Synchronizer) or device permission to access your Office 365 account.
If your admin has turned on multi-factor authentication for your organization, and you're using apps that connect to your Office 365 account, you'll need to generate an app password so the app can connect to Office 365. More info
