HI Kami,
If you have a WordPress site integrated with our PilotPress plugin you can do this by using "Page Protection" on your pages. When you are editing a page you can apply an Access Level you have set in ONTRAPORT in the Sites > WordPress section:
Notice the "On Error" drop down in that image? It allows you to redirect someone who does not have that access level to any other page on your WordPress site. You can create a sales page, a page with the opt-in form, etc. for people like your Person B who have the link but have not yet signed up to view the video.
You can upload videos in the ONTRAPORT Video Manager in Administration > Video Manager, and embed them in your WordPress page too, so you don't have to leave them on YouTube, or pay for a separate video hosting service.
ONTRAPORT is all about automation, so your opt in form can subscribe Person B to a Step Sequence that gives them access to the website access levels, then emails them their username and password.
