Maybe you mistaken the SteemConnect password with your account's master password.
That indeed is a very sensitive password and in my opinion never to be used, because, if leaked, it allows everything on your account, including changing the owner of the account.
No, my dear @gadrian, i didn’t mistaken. When you login through SteemConnect, you have to enter SteemConnect password. If someone steals that password, he can do what he wants with your account, right? That is, until you change all passwords with a master password. How is that more secure than using posting password, which is intended (as the name says) only for posting and voting? Do you understand what I’m talking about?

Thank you for your help, you have just answered to my question.
