1. Sharing Admin Passwords

Handing your admin password to a developer or contractor is one of the most common security mistakes. That password doesn't expire. If the relationship ends, you have to remember to change it — and many people don't.

Fix: Use Magic Login to generate one-time, expiring access links instead of sharing credentials.

2. Never Changing the "admin" Username

The default WordPress username "admin" is targeted by brute-force attacks constantly. If your username is admin, attackers already know half of your login credentials.

Fix: Create a new user with a unique username, assign it Administrator role, log in as that user, and delete the "admin" account.

3. Ignoring Plugin Updates

Outdated plugins are the #1 attack vector on WordPress sites. Security vulnerabilities are discovered and patched regularly — if you don't update, you're running known exploits.

Fix: Enable automatic background updates for plugins, or commit to a weekly update routine.

4. Using "http://" on Admin Pages

If your site doesn't have SSL enforced on the admin login page, credentials can be intercepted in transit on public Wi-Fi networks.

Fix: Get a free SSL certificate from Let's Encrypt and add define('FORCE_SSL_ADMIN', true); to your wp-config.php.

5. No Login Attempt Limiting

By default, WordPress allows unlimited login attempts. Brute-force bots will exploit this to try thousands of password combinations.

Fix: Install a plugin that limits login attempts, or use a firewall that blocks repeated failed logins at the server level.

Security doesn't have to be complex. Small, consistent improvements compound into a dramatically more secure site.
