Protecting WooCommerce Product Categories with a Password?

Hi,

I want to make certain product categories in my WooCommerce shop only viewable to people with a particular password.

The shop sells prints and the idea is that people who’ve had photos taken of their wedding or private event can access/purchase them in my WooCommerce shop by entering a password they’ve been given by the photographer.

I’m not sure how to go about this at all – or if this is even possible.

Thanks in advance for any help you may have.
