An Auth Key is your key that has the ability to send transaction from your Authereum account. It is capable of generating and broadcasting transactions to the Ethereum network and moving funds out of your Authereum account.
You can choose which keys of yours are Auth Keys in the "Settings" page of your Authereum account. We recommend keeping your Auth Key safe by using a hardware wallet or something with similar levels of protection.
