How do I set up an older cell phone, or use a smartphone without the Duo app installed?

Duo will work with any cell phone that can receive text (SMS) messages. When adding a device in this mode, first choose "Mobile Phone," and on the next screen enter the phone number. After confirming the phone number, set the phone type as "Other (and cell phones)" and the mobile device will be added.

Now that your phone has been added, whenever you see the Duo Authentication screen, you can select your Mobile phone as the device to use. After choosing Mobile, click on the green "Enter a Passcode" button, then in the blue bar at the bottom, click on the link to "Text me new codes. Take a look in your phone's text message app. You should see new message with a list of five codes you can use one time each. Enter one of the codes in the box shown below, and you're in!

What do I do if I don’t have my mobile phone with me?


Sometimes when prompted for re-authentication and the user selects push notification but did not receive one on iPhone. The Duo application icon was displayed on home screen with no indication of offloaded status. When icon was tapped, icon changed to superimposed standard iOS loading wheel. After loading was completed, push notification worked as normal. This may be a result of the application being considered as an "unused" application. Apple has not published the criteria on when it considers an app 'unused' but reports are common for apps unopened for as little as one week. In older devices that have 8 or 16gb of storage, this could be a common issue as those users are quickly faced with storage issues.

Mac version of Cisco AnyConnect does not allow setting the "30 Day" cookie in the Duo Authentication app

When Mac users connect to Lehigh's VPN server, they are prompted to enter their username and password, followed by a Duo 2FA screen. On the Duo screen there is a checkbox to "Remember me for 30 days" but it is greyed out, and can't be clicked on or otherwise selected. This is a known bug with the Mac version of Cisco Anyconnect, and we are waiting on a fix from the manufacturer.
