The Duo app on your smartphone or tablet can still provide a passcode without any data connection. Click on the down arrow symbol in your Duo app to generate a six-digit code to use to complete your two-factor authentication.
You can use that passcode to log in.
To generate a new passcode, click on the circular arrows.
Submit a service request with the ITS Helpdesk for assistance with Duo.
