Having to enter one's own address in the first step is confusing, because when someone goes onto the website to share a secret, they are thinking about the person they will share the secret with and sometimes enter their address without realising the necessity to get the auth token sent to their own address first.
While it isn't necessary to get the recipient's address in the first step, it would less confusing if both were entered, and the recipient's address was automatically filled in when creating the new secret.
