How you make the site private depends on where it’s hosted, but yes. On WordPress.com, you can just go to your site’s settings, and set it to Private. Scroll up just a little, and you’ll see how. It’s easy. On a self-hosted WordPress site, you need a plugin. The easiest one to use is My Private Site, which can be installed and configured in just a few clicks. Then you need to add a bunch of users to your site manually, but hey. It works, and it’s free. If you’re interested in other options, check out our write up of all the best website builders in 2022.
