Hi @sns ,

Thank you for posting in the community.

I'm sorry I couldn’t reproduce your question. In your question, you mentioned “SharePoint Environment copy” and “duplicate”, I don't really understand what these mean. Can you share how you created this SharePoint Site that you want to access? This will help me understand your question better, thanks for your understanding and cooperation!

 

I found some solutions about pop-up Windows Security, hope it will help you：

1. Add SharePoint Site’s URL to the Trusted sites zone. For a more specific procedure, please refer to this article: SharePoint Keeps Asking for Password Every time? - SharePoint Diary Note: Microsoft is providing this information as a convenience to you.

Please make sure that you completely understand the risk before retrieving any suggestions from the above link. 
2. Re-access SharePoint with a different browser or account and see if the Windows Security window pops up again.

Answer 2

Hi @sns,

I found some information about SharePoint Sites being marked as insecure.

If your browser is chrome 80. Chrome will report that a SharePoint site is not secure.

Here is the link to detailed information: SharePoint Online, Chrome, and "Insecure" sites

If the SharePoint site is still showing pages that the site is not secure, it is possible that there is a browser problem or a problem with the site's security certificate.

Here I found some ways to troubleshoot the problem, hope it can help you：

1.Clear bowser's cache.

2.Install security certificates.

• Click on “Continue to this website (not recommended).”
• Next to the red address bar, you should see the Certificate Erro****r option. Click on it.
• Click View certificates option in the popped-up information window.
• Choose Install Certificate option and then follow the instructions.
• Once the dialog shows up, click Yes to proceed.

3.Turn off “Warn about certificate address mismatch” feature.

• Open Control Panel.
• Go to Internet Options.
• Click the Advanced tab.
• Navigate to Security section and click on it.
• Find “Warn about certificate address mismatch“ option. If the box next to it is checked, remove the tick in order to disable these settings.
• Click Apply, then OK to save the changes.
