Allow Service Desk to Use Confluence as Knowledge Base w/o Anonymous

Without the ability to allow our customers access to the knowledge base w/o allowing anonymous access, this severely limit its usage when it comes to sensitive information such as password or other information that could potentially be seen by browsing internet user – when it comes to Atlassian Cloud.

Please figure out a way to limit KB access to only registered SD customers. I haven't use it before, but I see in Confluence that you can allow JIRA to handle user management? Is that a viable workaround? I know I can see SD Customer roles in JIRA but they don't exist in Confluence.
