The most common method is to use the push feature via the Duo Mobile app, whereby a challenge sent to your device requires that you confirm that your logon attempt is valid.If you have more than one device enrolled, you must specify which will receive the challenge. Click the drop-down arrow and then select a device where you have installed the Duo Mobile app.

Press the Send Me a Push button to proceed. An alert will be delivered to the smartphone or tablet selected as the Authenticator in the previous step.

Open the alert and click on the Approve button on your phone/tablet. Your screen will look similar to this:


After you approve the login request, you will be directed immediately to the service that you are trying to access.

If you have stopped receiving push notifications on Duo Mobile.

You may have trouble receiving push requests if there are network issues between your phone and the Duo service. Many phones have trouble determining whether to use the WiFi or cellular data channel when checking for push requests, and simply turning the phone to airplane mode and back to normal operating mode again often resolves these sort of issues, if there is a reliable internet connection available. Similarly, the issue may be resolved by turning off the WiFi connection on your device and using the cellular data connection.  Also, try opening the Duo application to verify if there is a push request waiting to be accepted.

Check the time and date on your phone and make sure they are correct. If the date and time on your phone are manually set, try changing your device's configuration to sync date and time automatically with the network.

Should neither of these actions help, see the Duo Knowledge Base for additional iOS and Android troubleshooting steps.

If you can't get Duo Push working on your own, you can log in with a passcode generated by the Duo Mobile app and send a new activation link to your phone. See the My Settings & Devices guide for instructions.

If you've tried the suggestions here but can't get Duo Push working or reactivate your device yourself, please contact the Duo administrator at to request reactivation of Duo Mobile.
