Is there a way

Is there a way to create Client Credentials or Sub Accounts on WPMUDEV.org? I am setting up a client who wants to manage their own site. After setup they will be completely on their own for day to day site management. So I dont want to use my credentials to setup/activate the WPMU dashboard on their site.
Is there a way to create Client Credentials or a Sub-Account on WPMU for my client? Or is there another way to go about this?
Thanks for your help.
