We updated our Pulse version to 7.1.0, and after that, it always asks for authentication. In previous versions, users without a username and password could access the site without authentication.
Has this changed in the new version? Does everyone now need to have a registered login? We use native registered logins.
Another aspect of this, from which Pulse version did you upgraded from?
On a newer version of Pulse, once it times out, it will now automatically rediect into the Pulse login page. This behaviour is controlled via the parameter RequireLogin in the Pulse.cfg file.
