The stronger approach, and the one I recommend, is to use one of the creation and storage plugins available on your browser. I think after a trial period, you have to pay for it, although Lots of people like RoboForm. I use the free version of Lastpass, and I recommend it for those of you who use Internet Explorer or Firefox. That will generate passwords for you.
A snap to move - If, for some reason, you want to relocate your site, such as a domain name change or a new hosting company, having your files at your fingertips can save you oodles of time, headache, and the demand for tech help.
You can create a firewall that blocks hackers from infiltrating go to my site your blogs. The hacker is prevented by the firewall from coming into your own files. You must have version of Apache. Upgrade your PHP also. It is essential that your system is full of upgrades.
