Cloning, as it applies to how to fix hacked wordpress site, is the act of creating an exact copy of your WordPress install. What's good is that you can do it in only a few clicks. There are a number of reasons. Here are just a few.
The stronger approach, and the one I recommend, is to use one of the creation and storage plugins available on your browser. Lots of people like RoboForm, but I believe after a trial period, you need to pay for it. I use the free version of Lastpass, and I recommend it for those of you who use Internet Explorer or Firefox. That will generate secure passwords for you.
What is the solution you my latest blog post should choose? Out of all of the options you can make, which one should you choose see this here and which one is right for you specifically now?
You can also get an SSL Encyption Security to your WordPress blogs. The SSL Security makes secure and encrypted communications with your site. You can also keep history of communication and the all of the cookies so that all transactions are recorded. Be certain that all your blogs get SSL security for maximum protection.
Do your homework and some searching, but if you're pressed for time and need to get this done once and for all, try the WordPress security plugin that I use. It is a relief to know that my site (and company!) are secure.
