Is there a website builder with the ability to password-protect a specific page?

Question

CMS

I want to make a site on the constructor, BUT at the moment there is no such function in my constructor as setting a password for a specific page (I use Ukit).
I found such functionality in the Wix editor, but there you can’t change the text that is displayed when the page is password-protected (it says something like “This is a guest area, enter the password.” But I need my contacts to be displayed).
Tell me, please, is there such a constructor where you can put a password on a specific page of the site and change the inscription that is displayed until the password is entered?
