Harvard uses DUO Security to provide two-step verification on HarvardKey.
There are several methods of authentication available depending on the device you are using for the second step of two-step verification.
To use the Duo Mobile app, you must first download the app from your platform's app store (Apple Store, Google Play, Windows Store).
After you set up and activate two-step verification, when you log in to a protected resource through the HarvardKey screen, you'll be prompted to verify your login using the secondary method of your choice.

For frequent international travelers or those working out of the country:
If you travel internationally and need to access resources protected by HarvardKey, you may wish to set up your two-step verification method to Duo Mobile passcode. Using Duo Mobile passcode (available on mobile phone or tablet), you can generate authenication codes even if you don't have Internet, wi-fi, or cellular connection.
Please note that if you are traveling internationally (or have an international phone number) and are using text messages as your method of two-step verification, you may be subject to your carrier's roaming charges for SMS messages.
