When connecting to the CADE Linux machines from on campus or the VPN, you may connect as usual with a password or an SSH key. When connecting from off campus, you’ll need both your CADE password and a one time code(2nd Factor Authentication).
To register an OTP app, log into the CADE machines from on-campus or the VPN and:
1. Go to Applications > CADE > Configure 2FA or from a terminal run configure-2fa.sh. This will display a QR Code on the screen.
2. Using the Duo app (or any other OTP app) scan the QR Code, where you will be asked to enter a 6-digit code.*
3. When remoting in from off campus, you will be prompted to enter your password, and then the OTP code on the next prompt.
NOTE: There is a bug in the Duo app. When initially registering the code, if it says that your code is invalid, close the Duo app and wait until the minute switches (or ~60 secs), then reopen the app and type the code again. This is only relevant during the initial setup.
