iPad asking for partner's password but not Mac

I can access my Win10 remote machine via TeamViewer on Mac w/o the partner asking for a password.

But when I try and access the same Win10 remote machine from the iPad app I'm asked to enter the partner's password.  I don't remember ever setting a password, don't know how to from the remote machine console or the web console nor do I see any way to recover or change the password.  Any ideas how to manage this issue to my iPad can access the remote machine?
