# Protected Apps and Subdomains ## Protected Sites If a site is not protected, anyone can access the site. When a site is protected, the following changes: - The site can only be accessed inside a Puter app iframe - Only users with explicit permission will be able to load the page associated with the site. ## Protected Apps If an app is not protected, anyone with the name of the app or its UUID will be able to access the app. If the app is **approved for listing** (todo: doc this) all users can access the app. If an app is protected, the following changes: - The app can only be "seen" (listed) by users with explicit permission. - App metadata can only be accessed by users with explicit permission. Note that an app being protected does not imply that the site is protected. If a user action results in an app being protected it should also result in the site (subdomain) being protected **if they own it**. If the site will not be protected the user should have some indication.
