Pre-requisites
1. Atlassian Guard (Atlassian Access) Subscription:
Atlassian Guard is an additional subscription applied across the Atlassian Cloud products like Jira Software, Jira Service Management, Jira Work Management, Confluence, and Bitbucket. It is needed for Single Sign-On (SSO) or any Cloud Service that comes under Atlassian Guard.
2. Domain Verification:
The first step of Atlassian Guard starts with the Domain Verification process to enforce SSO on the managed user accounts. This process verifies that you own a valid domain for managing the user accounts and use the same domain name for the email addresses.
