Having a generic login for all of my different password protected pages

I have a site for my service company where I have individually password protected pages and I was wondering if there was a way to have just one login in my navigation bar for all of the different clients to log into without having to navigate to there page and then entering a password.

I am trying to streamline so that the customers do not need to look hard for there login page it can be at the top of site.

I hope this makes sense. I am wanting because I will also have woocommerce worked into the site but I dont think I can customize individuals “My accounts page”

Any help is greatly appreciated and thanks in advance for any help.
