Two-factor authentication with Duo

Since March, 2019, Lehigh University has been helping faculty and staff protect the university's most vital institutional data with Two-factor authentication with Duo (2FA). Library and Technology Services is now making this service available to students.

What is 2FA with Duo?

Two-factor authentication with Duo (2FA) provides an additional layer of protection for your computer account by verifying your identity at logon using two factors: something you know (your password), plus something you physically have (a mobile phone, for example). This dramatically reduces the risk of someone else gaining control of your account, even if your password is compromised. You might already be familiar with this form of added security on some of your personal accounts.

Safeguarding your sensitive data

Lehigh’s Information Security Office identifies and deflects numerous attempts by cyber criminals to breach University systems and steal account credentials on a daily basis, many of which target student accounts. Implementing 2FA has been a key part of the University’s strategy to combat these attempts because it is very effective and often stops attackers in their tracks.

The effects of account compromise can be particularly harmful for students, since your private data may be stored on Google Drive and Lehigh Gmail. Attackers who gain access to student accounts could drop classes, alter enrollment and tuition, or attempt to acquire sensitive information that could be used to impersonate you.

How does 2FA with Duo work?

After you enroll in the Duo Security service, you will be prompted to enter your password, plus your Duo second factor, when you log into certain Lehigh sites or services, such as Course Site, GSuite applications including Gmail, or Banner.

Students are encouraged to enroll more than one device, such as a smartphone or tablet, or to generate and print backup codes in the event their only enrolled device is unavailable.
