without making any post on it at all

Yeah sure, @moecki.recovery for example has no posts or comments either.

But as written above, I recommend a 2nd account as recovery only for those who know what to do. I have gone through the procedure several times, but it would not be so easy for me either and I would have to read my own instructions again :-)

You have @steem as recovery, if I were you I would probably change this to @moecki.recovery because if the worst comes to the worst there is someone reliable at your side who can start the recovery and also help you with the next steps.

But it's your decision, because the private owner key is required for the change and this is usually stored offline, i.e. there is a certain risk in using it. For example, I never copy this key completely to the clipboard, but at least in two parts and I type some letters manually. So I really only take out the owner key if there are good reasons for doing so.

Another little hint, although I think you know it, the change will take effect after 30 days for security reasons. If an account is stolen, the thief could change the recovery and the account would be lost if the change takes effect immediately. Hence the 30 days.

So now I hope I haven't made you feel insecure, you'll make the right decision!
