Authenticate with Duo Push

  1. If you set up your device for Duo Push, when two-step authentication is requested Duo will know which organization is requesting authorization and will send a push notification to your device.
    • If your Android device is locked, you must unlock it then tap Approve on the device in order to see your website. If your iOS device is locked, you can approve the push without unlocking the device.
    • If the Approve button is not visible on your device, you may have to tap the green bar at the top of the screen to take action on a pending authorization.
