I back my blogs using a free plugin WP DB Backup up. I can restore my website if anything happens. I use WP Security Scan plugin that is free to scan my blog and WordPress Firewall to block asks that are suspicious-looking to fix hacked wordpress site.
You can look for software that will backup your database and files. You can restore your website with the use of your files and change, if hackers abruptly hack your website.
First in line is creating a password for your account. Passwords must be made with special characters and numbers. You see here may combine them and make small plus altered letters. Smarter passwords can be your gateway to zero hackers. Make difficult passwords that you can think of.
Take note of your new password! I recommend the version of the software *Roboform* to remember your passwords.
Don't use wp_ as a prefix for your own databases. Web hosting providers are eliminating that default now but if yours does not, fix wp_ to anything but that.
