Single Sign-on Integration with Atlassian products
Purpose
A Single Sign On system allows users to use a single login for multiple applications.
You can integrate Atlassian products with the following SSO systems:
Cloud deployment
SAML single sign-on is available when you subscribe to Atlassian Access .
Atlassian Access enables company-wide visibility, security, and control across your Atlassian Cloud products (Jira, Confluence, Trello and Bitbucket).
You can read more about SAML SSO with Atlassian Access here.
For Opsgenie, SSO is available through Standard and Enterprise plans.
Server & Data Center deployment
For our on-prem deployments, you have several options to enable SSO:
Data Center feature
Single Sign-On is one of the core features of our Data Center products. Check out this page to see how to enable SAML SSO for Jira, Bitbucket and Confluence Data Center
Using Crowd
If you need additional user management features, or if you're using a Server deployment, you'd need to use Crowd - Atlassian's single sign-on, authentication, authorization, application provisioning and identity management framework - see the Crowd documentation for more information on Crowd SSO and integrating it with Atlassian applications
Writing a custom authenticator
Jira and Confluence integrate with SSO system Seraph, the Atlassian authentication library. Seraph is a very simple, pluggable J2EE web application security framework developed by Atlassian and used in our products.
Marketplace app
Finally, you can also use a an app from our Marketplace
Delegate user management
Confluence can also delegate user management to use Jira logins, but this will not provide you with SSO.
