If you do not reset the password by the deadline on the banner at the top of the MyHacc portal when signed in (it expires every 140 days), you will be unable to access MyHACC until you reset the password. You can still use the password reset link on the MyHACC login page to reset your password, as long as you set up (and remember) the answers to the security questions.
If you have NOT set up (or do not remember) the answers to the security questions, you will have to contact the Support Center for assistance. The Support Center number is 21-HELP from any campus phone, or 717-780-2570 from off campus. Note that the Support Center is not available nights and weekends.
