Multiple password page layouts?

I’m looking for an implementation solution, and wondering if this plugin provides the functionality I need.

I need to be be able to password protect multiple pages, and for each page that is password-protected, the associated password-entry screen should have unique content/layout, along with a unique password.

Use case: each “private”, password-protected page is to be shared with a specific person or client. There will be a unique password for each page, and on the password-entry screen, I want to display a logo relevant to the person/org accessing it, as well as text instructions that may vary slightly for each user.
