While you could log into your MathWorks Account from home using the company email address, here is a description with a second (private) MathWorks Account
Step 1: Create a MathWorks Account (MWA) with your private contact information
Step 2: In your MWA, there is under “My Licenses” a button “associate licenses”. Follow the workflow. To my best knowledge, the administrator (which would be you) gets asked whether to accept this user. MathWorks Customer Service may be a middle man here.
