How To Restrict Access to a page, Force Login????

What can I use to restrict access to a page. I would like something that when users click on the page in the menu (if they are not already logged in) they are redirected to the /wp-admin to login, then sent back to the page they were trying to view.

I have found plugins that have allowed for an inset login for on the page, but I haven’t found one where the login is customizable so… If anyone has any suggestions on how this can be done, that would be super helpful. Thanks!
