Welcome to HarvardKey! HarvardKey is your new, secure login credential that gains you access to the University applications and services you use every day using just one login name and password. It only takes a few minutes to get your HarvardKey — and because HarvardKey is the University’s new lifetime credential for students, faculty, staff, and alumni, claim it once and you’re good for life.

1. Get Started

This process should take about 10 minutes to claim your HarvardKey and sync your devices. Make sure you first review the HarvardKey Claim Checklist before beginning. Then, visit and click on the Claim Your HarvardKey link.

On the Select Your User Type screen, select the HUID/eCommons Holders tab.

Click Continue.


2. Log In

Select, using the tabs, how you will login - using your HUID or eCommons credentials.

Enter your credentials. Click Login.

choose HUID or ecommons

3. Provide a Recovery Email

Next, you will be asked to provide at least one recovery email address. This address will be kept on file by HarvardKey in case you forget your password or login name, and it’s where HarvardKey will send reminders or instructions for password resets. Please note that you may not use a Harvard email address as a recovery email. Providing two recovery addresses isn’t required, but it’s a good idea in case you lose access to one of them at some point in the future.

When you’re done, click Continue.

4. Choose a Strong Password

You’re nearly finished. The final step is to choose your HarvardKey password. Keeping your personal data — and protected Harvard resources — safe is one of the biggest benefits of HarvardKey, so your password must:

  • Be at least 10 characters long (and can be up to 120 characters)
  • Contain five or more unique characters
  • Contain at least three of the following: an uppercase, lowercase, numeric, or special character

Your password must not include the following:

  • Your email, part of your name, or part of your address
  • Common words or acronyms of five or more letters, UNLESS your password is more than 20 characters long — in which case you can use words
  • Number sequences with four or more numbers

As you fill in your new password, green checkmarks will appear by the guidelines on the screen to help you. Please don’t use the same password for your HarvardKey that you use for anything else. Enter the new password again to confirm your choice. When you’re done, click Submit.

5. Success!

You’re all set! You’ll see a screen that displays your new HarvardKey details, which you can print for your records. You’ll also receive a confirmation email (at the recovery address you provided) from Harvard Identity and Access Management with your information, which you can save for future reference. 

Also, don’t forget to update your HarvardKey password in any password managers, apps that save your password, or other places where you may have your password stored. Forgetting to do this could result in your being locked out of your account, so be sure to visit the HarvardKey Claim Checklist and follow the instructions.

You may now use your HarvardKey to access a world of University services, all with the confidence of knowing your data — and protected Harvard information — is safe and secure. Thank you for claiming your new HarvardKey!
