Ladies and Gentlemen,
If you want to use the Atom feeds provided by this forum with authentication, e.g. because you are member of the beta group, you can use HTTP-based authentication as follows to get access to these boards via feeds:
username:password@url?auth=http
Replace ‘username’ and ‘password’ with your user name and password, replace ‘url’ with the feed URL that you can e.g. get via the RSS button in Safari. Adding the ‘?auth=http’ (resp. &auth=http when you are using a URL for a specific board) parameter makes phpBB3 read the authentication from the URL.
