Do I have to do anything to add Device Authentication?
The prompt will appear during the following activities
To authenticate your device, follow the prompt when it appears. It will ask you to accept, then a One Time password will be sent to your mobile phone number you have registered with Heritage. Enter in the One Time Password and your device will be authenticated.
This is a one time process. Once a device is authenticated you will not need to do it again unless you manually remove your device's authentication status in the app settings or disable SMS Security.
