If you used this Workshop for learning purposes and not for production you should always delete the created resources after you’re through all the steps.
In the AWS Management Console go to Settings, switch to the tab Management and click on Delete. You need to confirm that you understand that everything SSO related (including pushed users and groups) will be deleted.
Cleanup in Okta for a Free Developer Account is not required because no additional expenses are generated. Nevertheless, it’s a security best practice to delete unused users and applications in Okta. To delete the AWS IAM Identity Center Application, go in the Okta Admin Dashboard to Application -> Applications and click on Deactivate.
To delete it, click on INACTIVE and then Delete.
If you created additional users in Okta, go to Directory -> People and Deactive & Delete them.
