Membership plugin login page

This is basic question I'm sure, but how do I create a login page (not a public registration page) for users I've manually created for the membership plugin?

In this case, I do not want to have user registration publicly available. I simply want to create a private area of the site that only users I've created have access to. I have no problem setting up the protected content, etc. but can't figure out how I give the users a way to login to access the protected content. I didn't see this addressed in the user manual.

Is there a widget for login form? Short code to display form? A dedicated login page with form?

Thanks in advance...
