If you have an eCommons ID or XID, you can still use those credentials at the HarvardKey login screen to access the apps and services you’ve used them for in the past. Simply select the tab at the top of the HarvardKey login screen corresponding to the type of login you’d like to use. However, after you've claimed your HarvardKey, it's quick and convenient to use your HarvardKey to get into those resources — and it doesn’t mean the extra click to get to the tab!
The HUID/password (formerly PIN) login type will be retired during the spring of 2016. If you currently use your HUID and its associated password, you should claim your HarvardKey as soon as possible to avoid any disruption to your ability to access Harvard applications and services. Users will be informed on a rolling basis via email when their HUID/password credentials are set to expire.
