Hi,
Is it possible to set up Dropbox for Business with multi-factor account authentication as opposed to an oauth token?
If you use MFA to authenticate to Dropbox, you should have to go through the MFA process to get your access token.
The Splunk app for Dropbox uses Dropbox's REST endpoint to gather data which needs that access token. Here is more information about Dropbox's REST endpoint and the access token -> https://www.dropbox.com/developers/reference/oauth-guide
