Hello Bassam Al Dana,
Thank you for posting in Microsoft Community forum.
To avoid the prompt to select a certificate for authentication, you can do the following:
1.Ensure that the correct certificate is installed on the computer or device you are using for authentication.
2.Configure the application or service you are using to authenticate with the correct certificate.
3.If you are using a web browser, ensure that the website you are accessing is configured to use the correct certificate for authentication.
Tip: If the first certificate and second certificate are expired, you can delete them.Open certlm.msc or certmgr.msc and click Personal store to find them and delete them.After that you will see only second certificate when it authenticates every time.You can export the two certificates before you delete them if needed.
For example:
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
