How to Keep Your WordPress Website Secure

WordPress security sounds more technical than it is. The most common security threats websites face are not sophisticated targeted attacks. They are automated bots looking for sites that have not been updated or protected against well-known vulnerabilities. The good news is that defending against them is largely a matter of forming the right habits rather than learning advanced technical skills.

Here are the steps every WordPress site owner should take to secure their site.

 

Keep WordPress, themes, and plugins updated

Outdated software is the single most common cause of WordPress security incidents. When a vulnerability is discovered in a plugin or theme, it is typically patched in an update quickly. Sites that do not install updates remain exposed to exploits that target that vulnerability.

Enable automatic updates for WordPress core under Settings > General. For plugins and themes, either enable automatic updates individually in your plugin list or make a habit of checking for updates at least once a week. Delete any plugins or themes you are not actively using. Even inactive plugins can be exploited if they have vulnerabilities.

 

Use strong, unique passwords

Weak or reused passwords are among the most common routes into any online account, not just WordPress. Your WordPress admin password should be long, random, and used nowhere else. Use a password manager like Bitwarden or 1Password to generate and store strong passwords without needing to remember them. Enable two-factor authentication on your WordPress account if your security plugin supports it.

Also change the default admin username if you set one up as “admin” when installing WordPress. A different, less obvious username reduces the success rate of brute-force login attempts.

 

Install a security plugin

A security plugin adds protection layers that WordPress does not include out of the box. Wordfence is one of the most widely used options and includes a firewall that blocks known malicious traffic, malware scanning, and login attempt limiting. iThemes Security is another solid option. Both have free versions that cover the core security features most websites need.

Jetpack also includes basic security features like brute-force attack protection and downtime monitoring as part of its feature set if you are already using it.

 

Set up automated backups

No security setup is complete without backups. If something goes wrong, a recent backup is what allows you to restore your site to a working state rather than starting from scratch. UpdraftPlus is a widely used free plugin that can schedule automatic backups of your entire site and store them to Google Drive, Dropbox, or another cloud service of your choice.

Set backups to run daily if you publish new content regularly. Test a restore from backup once so you know the process works before you actually need it in an emergency.

 

Make sure your SSL certificate is active

Your site should load with https:// in the address bar, not http://. The SSL certificate encrypts data passing between your site and your visitors and is required to avoid browser security warnings that can push visitors away. Most reputable hosting providers include a free SSL certificate through Let's Encrypt. Check under your host's dashboard or SSL settings to confirm it is active and renewing automatically.

 

Limit login attempts

By default, WordPress allows unlimited login attempts, which makes it vulnerable to brute-force attacks where bots try thousands of username and password combinations. Your security plugin should include a setting to limit the number of failed login attempts from any single IP address before temporarily blocking further attempts. This one setting significantly reduces automated login attacks.

 

Use quality hosting

Your hosting environment is part of your security setup. Reputable hosts like SiteGround, WP Engine, and Kinsta include server-level security measures, automatic backups, and malware scanning that add a layer of protection beyond what you manage yourself. Budget shared hosting at the cheapest possible price often skips on these protections. A reliable host is one of the best security investments you can make.
