2-Step Verification helps protect your account from unauthorized access should someone manage to obtain your password. Even if a password is cracked, guessed, or otherwise stolen, an attacker can’t sign in without access to the user’s additional verification. After logging in with your username and password, you’ll be prompted to verify your identity—the second step—using something in your possession, such as a mobile phone with the Duo Mobile App, Duo Backup Code or Duo Token.

ATTENTION: The College is currently beginning the process of migrating and requiring all users to use Duo Security for 2-Step Verification

• All alumni and students not enrolled for courses began receiving an enrollment prompt on 12/19/22
• Students enrolled in courses are being prompted in segments for Duo prompt enrollment as of 1/16/23

All users are required to enroll to protect their personal data and improve overall security by enabling 2-Step verification. Many other Colleges and Universities have implemented 2-Step verification, as have most major service providers such as Google, Facebook, and Twitter. Please consider enabling 2-Step verification not only for the College but also for your other personal accounts.

The College has partnered with Duo Security to provide all users with the best 2-Step Verification experience possible.

Currently, the College does not support YubiKey’s Duo Security System for Students or Adjunct Faculty. All users are able to register a YubiKey as a Duo Security Key; however, it will not work when attempting to log in to the College’s computers, which use the Duo Windows Client. OIT does not provide support for any YubiKey unless it was provided to an employee by the College

Many College students and staff are already set up for 2-Step Verification and use Duo Mobile to generate an authentication code. The app is currently operating in ‘Third-Party’ mode, which does not provide the required level of protection. Please follow the enrollment steps to set up your device with Duo Mobile. Once set up, you can delete the ‘Third-Party’ token from the Duo Mobile app for delaGATE.

Please note that OIT cannot disable 2-Step Verification on any account. If users cannot access the account, they must follow the 2-Step Lockout procedure to gain access to the account.

Your account will lock after too many failed attempts to authenticate. The lock-out will automatically be removed after a period of time.

Users with 2-Step verification should always have a backup mode configured. All users must print a list of one-time-use verification codes during the enrollment process, as outlined in the video above.

If you do not have access to your backup verification codes, you should contact the OIT Support center during regular operating hours (Monday – Thursday, 7:30 a.m. – 10 p.m. EST, Friday, 7:30am to 5:00 pm and Saturday, 8 a.m. – 4:30 p.m. EST).

You will also be asked a series of authentication questions.

The Duo Mobile application uses a very small amount of data to send push notifications. If you received 500 push notifications per month, that would equate to 1 MB of data usage. Less than loading one web page to your mobile device. You may disable push notifications if you do not want to use any data; however, you will have to manually enter a code from the app as a passcode to log in. Data fees may be incurred during the installation of the application and during any updates if auto-update is enabled. We recommend connecting your device to the College wifi system when on campus.

The Duo Mobile app can generate passcodes with no Internet or data to generate codes. We recommend connecting your device to the College wifi system when on campus to ensure the best user experience.
