I back my blogs using a plugin WP DB Backup up. If anything happens I can always restore my blog. I use WP Security Scan plugin that is free to scan my site and WordPress Firewall to block asks that are suspicious-looking to fix hacked wordpress database.
Strong passwords - Do what you can to use a password, alpha-numeric, with upper and lower case and special characters. Easy to remember passwords are also easy to guess!
Should you ever want to migrate your website elsewhere, like a new web host, you'd have the ability to pull this off without a hitch, and also without needing to disturb your old site until the new one was set up and ready to roll.
Now we are getting into matters. Whenever you install WordPress, you need to official statement edit the file config-sample.php and rename it to config.php. You need to set up the database information there.
You do consider needing security when your website is new but you do need to protect your investment and yourself. Having a site go down and not having the ability to restore it may mean a big loss of consumers who probably won't remember to look for your website later and can not find you. Don't let this happen to you. Back your site up after you get it started, as the website is operational and schedule regular backups for as long. This way, you will have WordPress security and peace of mind.
