Yes, so far Plaid is the only aggregator that is supported with MFA because they have worked with us to establish a direct integration for authentication. Most aggregators use a “screen-scrape” technique, which means the member gives their credentials to the aggregator, and they in turn log in to the site as if they are the member, navigate the site, and copy or download needed data. MFA prevents this from working because the aggregator cannot receive and enter the one-time passcode.
To date, no other aggregators are supported once your credit union activates MFA. However, we are happy to work with any aggregator who wishes to take advantage of the same infrastructure as we use for our Plaid integration to establish a secure connection as an alternative to their current screen-scrape technique.
