IDs and Login Information

Knowing what online resources are available to you and how to access them is an important part of being a successful student. To help protect your student information, please remember to keep all your ID numbers, PINs, and passwords confidential.

As a Harvard Summer School student, you have two identification (ID) numbers and one or more associated login credentials:

DCE ID Number and DCEKey

Your DCE ID number uniquely identifies you within the Division of Continuing Education (DCE). It begins with the “@” symbol and is assigned to you the first time you create an online services account. 

Your DCEKey allows you initial access to DCE online applications, including online services. If you are new to Harvard and do not have a HarvardKey, you can create a DCEKey by selecting "create account" on the online services login page. If you already have a HarvardKey, you do not need to create a DCEKey. You may log in to DCE online applications using your HarvardKey.

Where Can I Find My DCE ID Number?

If you do not know your DCE ID number, you may request it from the online services login page. You may also visit Enrollment Services at 51 Brattle Street with a government-issued photo ID.

Where Can I Find My DCEKey?

Your DCEKey is the email address and password you provided when you first created your online services account or applied to a Harvard Extension or Summer School selective admissions program. If you do not remember your DCEKey password, you may reset it through the DCE login portal

Can I Log In Using My DCE ID Number and DCE PIN?

Returning students: The DCE ID and PIN login option will be retired from online services later this year. If you still use your DCE ID number and PIN to log in to online services, we strongly recommend you begin using your HarvardKey. If you do not have and are not yet eligible to claim a HarvardKey, you may create a DCEKey to use when logging in to DCE online applications. To create a DCEKey, simply log in to online services using your DCE ID and PIN and follow the instructions to create a DCEKey posted in the message box on the right-hand side of your student main menu. If you do not know your DCE PIN, you may reset it on the online services login page.

Harvard ID Number and HarvardKey

Your Harvard University ID number (HUID) uniquely identifies you within Harvard University and allows you to claim a HarvardKey. If you are new to Harvard, your Harvard ID number will be issued, activated, and viewable in online services generally within two business days of your course registration, beginning in mid-March.

Your HarvardKey is your login and password for most Harvard University web applications, services, and e-resources. Once your Harvard ID number is issued and activated, you can claim your HarvardKey at If you already have a HarvardKey, you do not need to claim a new one. 

Use your HarvardKey to access the following resources:

  • Summer School online services

  • Course websites and online video courses

  • Harvard computer and email accounts

  • Harvard library e-resources

  • Harvard ID Card Web Application

  • MessageMe, the Harvard emergency text notification system

Two-Step Verification

As part of claiming your HarvardKey, you will also set up two-step verification. Two-step verification adds an extra layer of security to your Harvard account and will be required to access HarvardKey-protected resources and applications this summer. With two-step verification, you verify your HarvardKey logins with a device in your possession (generally a mobile phone). For more information on the steps and requirements for using two-step verification, please visit the Harvard University Information Technology (HUIT) website.
