Multiple PW Protected Messages

I am creating two pages that both need to be password protected. One is for a fitness page and one is for another building amenities page. The client would like both to have slightly different wording.

Is there a good way to say something like

if page ID = XXXX then message = “Hello World”
else if page ID = XXXX then message = “Nom Nom”

The page I need help with: [log in to see the link]
