On Primo VE you can generate a QR Code for the page you are viewing.

If the page is a search the QR Code link works, once scanned the search is replicated.
If the page is from your account, LibraryCare, My Loans, My Requests, when the code is scanned it invokes authentication.

However, for Favourites, when the code is scanned it shows a "blank" screen if the user isn't already authenticated on the scanning device.

I would like to propose that the link generated for Favourites invokes authentication in the same way as pages for Loans, Requests etc,
