I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.
Finally, installing the secure your wordpress website Scan plugin alert you to anything that you may have missed, and will check all this for you. Additionally, it will tell you that a user named"admin" exists. Needless to say, that is the user name. You can follow a link and find directions if you desire. Personally, I believe that a strong password is protection that is good, and since I followed those steps, there have been no attacks on the sites that I run.

There is a section of config-sample.php that's headed"Authentication Unique Keys." There are. A hyperlink is inside that section of code.

There are always going to be risks being online (or even just being alive!) And it's easy to get caught up in the panic. We put the breaks on when we get caught up in the fear. This isn't a reaction that is good. Simply take some common sense precautions forge ahead. It will need to be dealt with then, if something bad does happen and of quaking in your boots 23, no amount will have helped. If nothing does, all is good and you haven't made yourself sick with worry.
