    What is it and how do I claim it?

    The majority of Reunion information will be provided electronically. If you haven't already, claim your HarvardKey, the University’s secure credential for accessing online applications and services, and update your contact information.

    How do I claim my HarvardKey?

    Visit key.harvard.edu and follow the step-by-step instructions. You will need your Harvard Alumni Association ID (HAA ID), class year(s), and preferred email address on file. You can also watch a step-by-step tutorial video »

    Where do I find my HAA ID and preferred email address?

    Your HAA ID number can be found in the footer of recent emails from the HMS Office of Alumni Affairs and Development and the Harvard Alumni Association, including the monthly Harvard Alumni Gazette or the HAA eVents. The preferred email address on file is the address that received the email.

    What if I need help claiming my HarvardKey?
