How do I create a payment PIN in Trailhead so my Mom/Dad can view my account balance?

SOLUTION
Visit the Bursar's Office web page (https://www.mines.edu/controllers-office/accounts-receivable-and-cashiering) for details.

NOTES
After you set up your Parent PIN, your parent will need to login to CASHNet (https://commerce.cashnet.com/minespay), not Trailhead, to access the authorized information.
