If you're really worried about this, use two accounts. One to post articles, etc. with, and one to manage the site. The admin account can have a secure, hidden, username and the public author based one will not have permissions at a high enough level to do a lot of damage to your site. In fact you can even do this and never login as the lower level user at all, just set the author of the post to your secondary user account.
