To access Alumni resources, you must claim your HarvardKey. Once you have claimed your HarvardKey, you can also use it to access resources that you previously accessed with your HUID and its associated password. There is no reason to wait to claim your HarvardKey.
Once you have claimed your HarvardKey, whenever you are served with a HarvardKey login screen, login by selecting the HarvardKey tab and entering your login name and HarvardKey password. This will gain you access to all the resources for which you previously used your HUID and password to access. Alternatively, you can also select the HUID tab and enter your HUID and HarvardKey password.
If you are prompted to enter your HUID and password to access a Harvard system that doesn’t use the HarvardKey login screen (such as VPN), your HUID and HarvardKey password will work.
