How do I recover the Bitlocker key for my University managed computer?

From another computer:

• Log in to https://myaccount.microsoft.com/device-list
• You will see a list of computers that have you listed as the primary user
• If there are multiple devices on the list, you'll need to identify the correct computer:
  • Click on each computer then choose View Bitlocker Keys
  • Look at the Key ID to see if it matches the number displayed on the Bitlocker recovery screen
  • The Key ID that matches is the one you need to use
    
• Click Show recovery key
  
  
• Enter the key on the Bitlocker recovery page on your computer
