Sorry you are having trouble with the API Key. You can access the API Key by logging back into your account at:?https://console.1on1secure.com/login.php
On the main screen when you login on the upper right corner you will see your API Key. Just click on it once and it will automatically be copied. Next you can go back to your WordPress account and paste the API Key into the plugin settings page for 1on1 Secure.
Hope that helps!
