How to Connect with SSH Using Duo 2-Factor Authentication
SSH (Secure Shell) is used to connect to the ݮƵCloud. If you wish to connect to ݮƵusing SSH you will need to first install the Duo app on a device, verify your email, and register a device (such as a smartphone) through the ݮƵwebsite. If you have not yet registered for Duo two-factor authentication and you attempt to log in to wrds-cloud.wharton.upenn.edu via SSH, you will receive an “Access Denied” message.
Instructions
- First, follow these steps to register your device and set up Duo 2FA: How to Log In to ݮƵUsing Two-Factor Authentication.
A mobile device is not required; it is also possible to register a landline. Any problems? Review the Troubleshooting section and FAQ. - If you currently use SSH keys to connect, you will need to use the following new hostname to log in: wrds-cloud-sshkey.wharton.upenn.edu. If you currently use SSH with your username and password, you will continue to use the same hostname as you do now: wrds-cloud.wharton.upenn.edu.
- After entering your username and password, you will be prompted to choose a two-factor authentication method. You will be presented with the options that you selected when you registered your device. Follow the directions on the screen. (See sample prompt below).

At the prompt, you can either:
- Enter a passcode if one has been sent to your device. You should now be successfully logged in to the ݮƵCloud.
- Enter 1 to receive a Duo Push alert to your device. An alert is sent to your device, asking if you are logging in to a UNIX application. Open the Duo Mobile app on your device and acknowledge the message. You should now be successfully logged in to the ݮƵCloud
- Enter 2 to have a passcode sent to your device. You will receive a text message with the SMS passcode. Enter the passcode. You should now be successfully logged in to the ݮƵCloud.
If you are having trouble receiving the Duo Push, check the settings on your device to ensure that the Duo Mobile app has notifications enabled. In addition, verify that you are connected to a reliable Wi-Fi or cellular connection.
Managing Your Devices
To manage enrollment of your duo devices, please log in from an unremembered device and select "Other Options" instead of continuing to log in. If you do not have an unremembered device, you may try using incognito mode on your browser. If you cannot do either of these, please contact ݮƵsupport.
