## Code

```php
if ( ! is_multisite() ) {
    return;
}

$wpide_private_sites = array(); // Blog IDs that only members can view, e.g. array( 3, 7 ).

if ( ! in_array( get_current_blog_id(), $wpide_private_sites, true ) ) {
    return;
}

add_action( 'template_redirect', function () {
    if ( is_user_logged_in() && ( is_user_member_of_blog() || is_super_admin() ) ) {
        return;
    }

    if ( ! is_user_logged_in() ) {
        auth_redirect();
    }

    wp_die( esc_html__( 'This site is only open to its members.' ), esc_html__( 'Members only' ), array( 'response' => 403 ) );
}, 1 );

add_filter( 'rest_authentication_errors', function ( $result ) {
    if ( ! empty( $result ) || ( is_user_logged_in() && ( is_user_member_of_blog() || is_super_admin() ) ) ) {
        return $result;
    }

    return new WP_Error( 'wpide_members_only', __( 'This site is only open to its members.' ), array( 'status' => 401 ) );
} );
```

## Notes

List blog IDs in $wpide_private_sites. Feeds and the REST API are covered too; super admins always have access.
