Hi there!
If you complete a learning path on a MongoDB University account with an email address that’s different from the one your GitHub Student Developer Pack benefits are under, you can still access the free certification voucher. No need to link accounts.
To do so, you must verify that you have active GitHub Student Developer Pack benefits by entering your GitHub credentials on mongodb.com/students.
After successfully entering your credentials, the webpage will show 2 tiles, one for MongoDB Atlas credits and one for MongoDB certification.
In the text for the certification tile, there’s a link to a form that you can fill out to request a free certification voucher.
The form asks for some information (your MongoDB University account email address, your GitHub username, etc.) so that we can verify that you are eligible for a voucher. It usually takes 2-5 for us to process manual certification voucher applications so we appreciate your patience!
Hope this answers your question.
