Hi, Hive account@coquiunlimited, sorry we didn't see your comment right away. We use different method for working with user accounts - you use your active key one time to authorize posting permission to our application (account Hive account@oneplace.app). After that we can sign all your account votes and posts with our own posting key and we do not store or ask again to enter private keys, until you want to stop using account in our app and revoke posting permission. We will describe this procedure in more details in a separate post.
