Hi, Shubham.
Thank you for contacting the Microsoft community.
As we understand from your post, you would like to request your MCID and Access Code to update the Microsoft account associated with your Certification Profile. We are happy to help!
To properly assist you, we have sent you a Private Message requesting more information. Keep in mind that this is a public forum, so it would be best not to share any personal information outside of the Private Message.
