Connected accounts are any third-party services (Google, Facebook, Twitter) that you have linked to your Kinja account.
You can connect new, and disconnect existing accounts in your Account Settings page, accessed from the user menu.
You can add or remove a connected account at any time by clicking on the service name. You will always need to have at least one account connected -- this account is your login account. You can learn more about your login account here.
Connected accounts are not available to Burners.
