Will Synch Users plugin work with users registered on the master site via M2?

I am trying to set up a network of member sites that share users registered at the master site through M2 paid memberships. Multisite is not an option as budgeting for this project does not allow for dedicated IP and I lack the skills to set up multisite with domain mapping on a vps. In any event, I am needing to know if the combo of these two plugins will accomplish what I need.
Also, if anyone has a comprehensive tutorial for how to set up wordpress in subdomain multisite mode in a DO droplet that would be amazing!

Thanks all!
