Password Protected Pages Wordpress

I would like to use the Duo Two Factor Plugin on our Wordpress site. For each of our clients we have a password protected page on our site. Currently I give each client their unique URL and a password. What I would like to do is introduce two factor security for the pages.

I have two questions:

  • Will I be able to add two factor security to the password protected pages?

  • What would the steps be, both for me to set up and for the client?

Many thanks for your assistance.
