Much like the tool tip explains, a Private event will not appear in your Events page, be promoted as part of the Banner or Pop-Up and is only accessible via the direct link to the event.

Past Events can also be made private which will remove them from the Events page.

With the option to require users to log in before they are able to view the stream, a pop up will prompt the user to either log in to an existing account or register a new account on your website. This is a great way to capture information and retarget shoppers at a later time.

Adding a password, will require the password be given before customers are able to view the event page to RSVP or to watch the event - either live or recorded. Once you have added the password to the event, make sure you share it with the people that need it so they can access your content.

Customers will see a pop-up that will block access to the event RSVP and content until they add the password: 

Paid Events
Currently paid events are only available to customers with a Shopify integration.

You have the option of tying your event to a product or package that must be purchased before the RSVP will be processed.

To set it up: 
Under advanced 'Visibility' tab, select "Paid" from the 'Event Accessibility' box on the right. Then select the product that you would like tied to the event:

Make sure to Publish your changes if it is an existing event. If it is a new event, proceed with your setup.

What a Website Visitor sees with a Paid Event:

When a website visitor clicks on the event tile from your Events page, they will see a pop up that says the product must be purchased. If they have previously made the purchase, they only need to login to verify the purchase. If not, they will be taken to the checkout flow.

Once the purchased has been verified (either by logging in or by purchasing directly from the pop-up), the website visitor will be RSVP'd for the event.
