How to authenticate with duo push
Once you try to login, you should be prompted to receive a duo push. Once that happens you need to open up your duo application and should be greeted with a green banner.
You have to select the green banner and then you will be told which service you are getting the notification for. You should also be prompted to either approve or deny the authentication. To login you will have to approve the push notification you have received. After that you should be let in.
