Authenticate with Duo Push

  1. If you are using a browser that you previously used to authenticate, you will be presented with the last-used authentication method. If Duo Push was your last-used authentication method, a login request will be sent to your device. 

    • If Duo Push was not your last-used authentication method, click Other options.

    • In the Other options menu, select the Duo Push option.

  2. If your device is locked, you must unlock it and tap Approve on the device to see your website.

  3. Once you have authenticated, you might see a screen that asks if you want to trust the browser. You’ll have the option to select “Yes, trust browser.” This takes the place of the “Remember Me” screen. 

    • If you click Yes, trust browser the browser will automatically remember you, and you will not be prompted to authenticate for that application or service for the next 90 days.

    • If you select No, do not trust this browser, you will still authenticate and continue onto your desired site; however, you will be prompted to re-authenticate each time you log into an application on that browser. 

    • Remember, public or shared computers shouldn’t be saved as trusted browsers.
