You should use the "forget your username or password" option on the front page of Harvard Careers. We recommend candidates set their security questions carefully, utilizing question/answer combinations they can easily reference later. Note: please be sure to disable any autofill settings or password manager applications, especially if you recently changed your password. You can reset your security questions upon re-entering your account under your Dashboard.
If you are unable to unlock your account using your security questions, please email ithelp@harvard.edu.
