To use Cornell's Virtual Private Network (VPN) with campus networks and services, you must use Cisco AnyConnect VPN software. See How to Install Cisco VPN Software for instructions.

3. In the Cisco AnyConnect window:
   • In the Group box, select Two-Step_Login. This will be required for all VPNs as of July 15, 2021, but you can use it any time.
   • In the User Name box, enter your Cornell NetID or GuestID.
     Note: If you are connecting to a departmental VPN, enter your NetID and the name of the departmental group, for example, pqs665@departmental_group_name.
   • In the Password box, enter your NetID password.
   • In the DUO Passcode (push/SMS/phone) box, type one of the following options to complete Two-Step Login:
     • push to send a login request to your smartphone or other mobile device
     • phone to call you on your mobile phone or landline
     • SMS to receive a new set of passcodes. (You'll need to log in again.)
     • An actual numeric passcode
       
       
4. Click OK.
5. If you entered push or phone, complete the Two-Step Login process.
   You're now connected to the VPN.

If you don't have access to the default device you use for Two-Step Login, you can use an alternate device. In Step 3 above, enter the method you use to complete Two-Step Login followed by a number, for example push2 or phone2. To see the devices you have set up and the numbers to use for each, go to Your Two-Step Login Devices and use the number in the Device Number column.
