How to Secure Your WordPress Website: A Beginner’s Guide

WordPress powers more than 40% of all websites on the internet. That popularity also makes it one of the most targeted platforms by hackers. The good news is that most WordPress security issues are preventable — and you don’t need to be a developer to handle them.

Here’s a practical, plain-English guide to keeping your WordPress site safe.

Keep Everything Updated

This is the single most effective thing you can do. Outdated WordPress core, themes, and plugins are the most common entry point for attackers. Updates regularly include patches for known security vulnerabilities — so delaying them is essentially leaving a known door unlocked.

Set a reminder to check for updates weekly, or use a managed WordPress hosting plan that handles core updates automatically. Our guide on choosing the right WordPress hosting plan covers what managed hosting includes and whether it’s worth it for your situation.

Use a Strong, Unique Password for Your Admin Account

“Admin” as a username and “password123” as a password is unfortunately still common — and attackers know it. Use a strong, randomly generated password for your WordPress admin account and don’t reuse it anywhere else. A password manager makes this easy to maintain without having to memorize anything.

Also consider changing your admin username from the default “admin” to something less predictable.

Enable Two-Factor Authentication

Even a strong password can be compromised. Two-factor authentication (2FA) adds a second layer of verification — usually a code sent to your phone — so that knowing your password alone isn’t enough to break in. Plugins like WP 2FA or Google Authenticator make this easy to set up without technical knowledge.

Install a Security Plugin

A good security plugin monitors your site for suspicious activity, blocks malicious login attempts, scans for malware, and alerts you if something looks wrong. Wordfence and Solid Security (formerly iThemes Security) are two of the most widely used and trusted options. Both have free tiers that cover the essentials for most sites.

Set Up Automatic Backups

Security isn’t just about keeping attackers out — it’s also about being able to recover quickly if something goes wrong. Automatic daily backups stored somewhere separate from your main server mean that even a worst-case scenario (a hack, a botched update, accidental deletion) doesn’t mean permanent data loss.

Plugins like UpdraftPlus make automated off-site backups straightforward to configure. For a technical overview of WordPress security hardening, WordPress.org’s hardening guide is the most authoritative reference available.

Limit Login Attempts

By default, WordPress allows unlimited login attempts. Attackers use automated tools to try thousands of username and password combinations until one works — a technique called brute-force attack. Limiting login attempts (using a plugin or your hosting provider’s firewall) blocks these attempts before they get far.

The Bottom Line

WordPress security isn’t about doing everything perfectly from day one. It’s about layering simple protections that make your site a much harder target than the next one. Start with updates, strong passwords, and a security plugin — those three alone cover the most common vulnerabilities. Everything else builds on that foundation.
