Answer:
Yes, the password protection and restricted email features can be used together. To do this, you'll first need to enable the restricted email feature, followed by enabling password protection.
To clarify, the restricted email feature is designed to gather emails from people who want access to your content. However, it doesn't allow you to restrict access based on specific email addresses. This is where password protection becomes useful—it ensures that only those with the correct password can access the protected content.
By combining these features, you can collect emails and add an extra layer of security to your content.
