As Harvard University’s primary login credential, HarvardKey grants you access to the applications and services you use every day with a single login name and password. As more and more applications and services in the Harvard ecosystem adopt HarvardKey access, your HarvardKey will grant you access to a growing number of resources. However, you will sometimes see the option to log in using other types of credentials too. If you have a different Harvard credential type – eCommons or XID, for example - you can use those to log in to resources that offer those options.
Users who haven't yet claimed a HarvardKey can continue to log in at all HarvardKey login screens using their usual credentials simply by clicking the appropriate tab at the top of the screen.
