You Do Not Have a Smartphone

If you do not have a smartphone and need to authenticate with Two-Step Login, your choices include:

• USB security key
• hardware token (if you use CU VPN, choose the hardware token)

You Have Duo and Your Smartphone

Sometimes you might have connectivity on a device, but no mobile service (for example, you work in a basement lab with no Wi-Fi/cell connectivity). In cases like this, you can generate a passcode on the Duo mobile app to log in to a Cornell service. To do so:

Start the login process on your Cornell service. When it prompts you to enter Duo code, select Other options.

Select Duo Mobile Passcode

It will ask for a six-digit code. 

Open Duo on your smartphone

Select the Cornell University account.

You will see a six-digit passcode. Enter this passcode in your web browser where you are logging in.
