Similar codes can be found online:

//template_redirect动作钩子是一定会执行的，所以用这个钩子对全站有效
add_action( 'template_redirect', 'ashuwp_show_only_login', 0 );
function ashuwp_show_only_login(){
//判断登录，about页面就允许访问
if( !is_page('about') && !is_user_logged_in() ){
auth_redirect(); //跳转到登录页面
exit();
}
}

The code comes from: www.ashuwp.com

The original code only allows non-logged-in users to access the specified page or jump directly to login.

Simple change, add a judgment in_category, only allow access to archive pages and articles in the specified category.

// 首页和指定分类文章可以访问
add_action( 'template_redirect', 'ashuwp_show_only_login', 0 );
function ashuwp_show_only_login(){
//判断登录，只允许访问ID为3和2的分类文章
if( !in_category( array( 3,2 ) ) && !is_home() && !is_user_logged_in() ){
auth_redirect(); //跳转到登录页面
exit();
}
}

By default, non-logged-in users are only allowed to access the website homepage and category archive pages and articles with category IDs 3 and 2, otherwise they will jump to the login page.

Remove the exclamation point in front of !in_category and change it to in_category. On the contrary, access to category articles with category IDs 3 and 2 will jump to login, and other articles can be accessed normally.

The code is added to the theme function template functions.php.
