Exclude pages - Password Protected plugin

I have tried getting help with this on WordPress.org but no luck, so now I am hoping that the team here on WPMU DEV can assist me :slight_smile:

I am wondering if somebody knows how to exclude a page from the Password Protected plugin. I have a "coming soon" page that I would like visitors to see, but to enter the rest of the site you need a password.

According to http://wordpress.org/support/topic/exclude-pages-14?replies=3 there is a possibility to filter the option 'password_protected_status' and return a value of false on the specific pages you want to be accessible. However, I am not very good at php so I need some help with this.

Cheers,
Andréa
