This Register Your Smartphone for 2FA video will show you how to register your smartphone for two-factor authentication. The following article is the transcript of the video, along with screenshots if you would like to read a brief article instead.
To improve the security of your CNetID, set up your smartphone to use two-factor authentication (2FA) and ensure you're the only one who can access your account, even if someone knows your password.
- To enroll in 2FA, visit 2fa.uchicago.edu and click Go to 2Factor.
- Log in by entering your CNetID and password. This is the first layer of security or the first factor of 2FA.
- If you have not previously enrolled in 2FA, you will be prompted to Register a Device.
- Select the Mobile Phone option, then select Continue. You can find information on the use of tokens in the Two-Factor Authentication (2FA) FAQ.
- Enter your mobile phone number and click Continue.
- Select your device's operating system and click Continue. (In this example, the operating system is Android.)
- You will be prompted to download the Duo Mobile App to your phone, either through the App Store (iPhone) or Google Play Store (Android).
- Confirm you have installed the app on your phone by checking the box on the bottom of the screen, then select Continue.
- The Duo barcode appears on the next screen. Open the Duo Mobile app on your smartphone and scan the barcode.
- For Android, press the plus sign in the upper-right corner of the app. For iPhone, follow the prompts, then scan the barcode from your computer screen using your phone's camera.
When the barcode is scanned correctly, you will see an acknowledgment (shown below) that your device has been successfully registered. Select Enroll Another Device to immediately enroll another device.
- If you choose not to enroll another device at this time, select Done. However, you are strongly encouraged to register more than one device in case you lose your device or don't have it with you when you need it. See the What if I lose my phone? section in the Two-Factor Authentication (2FA) FAQ to learn what to do if your device(s) is missing.
