+## GitLab Pages access control **[CORE ONLY]**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/issues/33422) in GitLab 11.5.
+
+NOTE: **Note:**
+GitLab Pages access control is not activated on GitLab.com.
+
+You can enable Pages access control on your project, so that only
+[members of your project](../../permissions.md#project-members-permissions)
+(at least Guest) can access your website:
+
+1. Navigate to your project's **Settings > General > Permissions**.
+1. Toggle the **Pages** button to enable the access control.
+
+    NOTE: **Note:**
+    If you don't see the toggle button, that means that it's not enabled.
+    Ask your administrator to [enable it](../../../administration/pages/index.md#access-control).
+
+1. The Pages access control dropdown allows you to set who can view pages hosted
+   with GitLab Pages, depending on your project's visibility:
+
+    - If your project is private:
+      - **Only project members**: Only project members will be able to browse the website.
+      - **Everyone**: Everyone, both logged into and logged out of GitLab, will be able to browse the website, no matter their project membership.
+    - If your project is internal:
+      - **Only project members**: Only project members will be able to browse the website.
+      - **Everyone with access**: Everyone logged into GitLab will be able to browse the website, no matter their project membership.
+      - **Everyone**: Everyone, both logged into and logged out of GitLab, will be able to browse the website, no matter their project membership.
+    - If your project is public:
+      - **Only project members**: Only project members will be able to browse the website.
+      - **Everyone with access**: Everyone, both logged into and logged out of GitLab, will be able to browse the website, no matter their project membership.
