Issue/Introduction

Customer has worked through some SameSite and X-Frame-Options issues with Chrome browser, but is unable to authenticate as expected when using Incognito mode.  Customer is asking if there are any ACO (Agent Configuration Object) parameters to address this.

Resolution

There are no ACO parameters specific to Incognito mode or other browser's private mode. The Chrome instance in question was configured to block third party cookies and reverting this setting to allow third-party cookies resolved the issue.
