Selecting this option will allow you to bypass DUO authentication for the next 60 days. This only works if cookies are enabled, and you are logging in from the same computer and browser. You will still be prompted to verify once – with your username and password. You will not be able to access your settings on that particular browser during the 60 days. Please note that if you have tools or policies running that regularly delete or clean cookies, the remember me feature will not work. If you do need to access your settings (perhaps to add another device), just try another browser or visit the FDU Self-Service Portal. Remember me will not work if your browser is set to private browsing mode.

The remember me feature relies on browser cookies. For remember me to work, your Internet browser must allow cookies to be stored. Visit your browser content settings to ensure cookies are being stored. Some departments on campus do not allow cookies to be stored. If the remember me feature does not work on your browser, check with desktop support in your area.

You may have trouble receiving push requests if there are network issues between your phone and Duo’s service. Many phones have difficulty determining whether to use the Wi-Fi 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 types of issues, if there is a reliable internet connection available. Similarly, the issue may be resolved by turning off the Wi-Fi connection on your device and using the cellular data connection.

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.

The steps that Push Troubleshooting performs automatically are as follows:

• Check device settings.
• Check internet connectivity.
• Check that the device can contact Duo’s cloud service.
• Attempts to send a test Duo Push notification.

Should none 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.

If you’ve tried the suggestions here but can’t get Duo Push working or reactivate your device yourself, please contact the Fairleigh Dickinson University Technical Assistance Center (UTAC).
