So Update! We’ve phased out SSO (Single Sign On)- and it should be just your discourse account.
There are some other options we have access too:
All new users must be explicitly invited by trusted users or staff. Public registration is disabled.
Require authentication to read content on this site, disallow anonymous access.
must approve users
Staff must approve all new user accounts before they are allowed to access the site.
User must type this code to be allowed account registration, ignored when empty (case-insensitive)
I’ve set “Login Required” to true, but the other options are things we can talk about next Monday.
