1. If I register 3 domains can I have single sign on for only one of the domains?

I have three separate domains that share an ATLASSIAN Suite, from Confluence to JIRA.

I would like to be able to setup one of those  domains for single sign on. Is this possible?

Hi @Montez Knowles , 

it's now possible to have different authentication policies with Atlassian Access, as described here : https://confluence.atlassian.com/cloud/authentication-policies-1018779823.html

Let me know if this helps,
