Nope.

Without the private keys, the password is useless. That doesn't mean one should broadcast it in the open. It's an additional security step.

The same password unlocking protection is used by Steem Keychain, and by some of the most powerful password management tools existent online.

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.

Maybe you mistaken the SteemConnect password with your account's master password.

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.
