Google 2-Step is required for your
NCSU alumni account. You will get an error message saying, "Couldn't sign you in. Your sign-in settings don't meet your organization's 2-Step Verification policy. Contact your admin for more info," or "Contact your domain admin for help," if you did not set up Google 2-Step during the enrollment window or if you forgot your password before setting up Google 2-Step. In either case, you will need to recover your alumni account.
Going through the alumni account recovery process will reset your password and will re-open Google 2-Step enrollment.
