Client Migration with WPEngine Site Migration

The agency I work for is semi-amicably parting ways with a client for repeated non-payment. The (non-technical) client would like us to migrate their site from our hosting to WPEngine, using the WPEngine Site Migration plugin.

My concern with this is that duplicating the database is going to bring my credentials along with it, which I don't want for a variety of reasons. Am I mistaken to think the migration tool is going to also migrate my login? Is there a way to prevent this?

What would be a better alternative?
