Please Note: the XID service was retired on July 27, 2021.
Active XID holders' accounts were migrated to HarvardKey - but a password reset is needed in order to activate the account. Directions are here: https://iam.harvard.edu/what-happened-my-xid If you need help call the HUIT Service Desk at 617-495-7777 or email firstname.lastname@example.org
Applications that allowed XID logins will use HarvardKey instead - there will not be a separate tab for XID login anymore.
Please email email@example.com if you have any questions or need to use the replacement service for XID: HarvardKey Light.
