The HarvardKey PIN (password) System is an authentication system. It is used by multiple web sites and web applications affiliated with the University in order to provide a secure means for Harvard users to access online resources. One of the benefits of this system is that it allows a user to access many different systems using a single login ID and Password. To claim your Key, go here.
Your HarvardKey can be used to access the wireless network, your my.gse.harvard.edu account, course iSites, and other university resources. An XID can be used to access particular systems, or resources by arrangement with the administrators of those resources.
Please note: The XID will not automatically grant you access to any system, but will be used to grant you access if an administrator deems it appropriate to do so.
