The Atlassian Community can help you and your team get more value out of Atlassian products and practices.
Configured Azure Atlassian Cloud Single signon option, after enabled in Cloud, now I locked out myself from login to Cloud, seems the integration configuration wasn't quite right, Please let me know how can I turn off the SAML settings in Cloud.
Do you have another Atlassian account (not belonging to the domain that you might have verified for your organization) that can be used to login to your Atlassian Cloud site? This Atlassian account should be a Site admin and an Organization admin.
If there is no such account existing, please contact Atlassian Support for help: https://support.atlassian.com/contact/
Hope it helps!
