Complete WordPress Security Guide 2026
Val Lazarev, ALMA WebPro
WordPress sites are a target. Hackers exploit outdated plugins, weak passwords, and missing backups. Here’s a complete security guide to protect your business.
1) Keep Everything Updated
- ✅WordPress core: Update immediately when new versions release (usually monthly).
- ✅Plugins & themes: Disable auto-updates only for premium plugins. Delete unused plugins.
- ✅Server software: Ask your host (Bluehost, SiteGround) to keep PHP/MySQL current.
2) Enforce Strong Passwords & Two-Factor Authentication
- ✅Admin password: 16+ characters, mix of uppercase, numbers, symbols.
- ✅Two-factor auth (2FA): Require password + phone code to log in. Use free plugin like Wordfence or Two Factor Authentication by Google.
- ✅Remove default “admin” username: Use unique usernames.
3) Daily Automated Backups
- ✅Daily backups: Most hosts (Bluehost, SiteGround) include automated backups. Verify they’re enabled.
- ✅Off-site backup: Download copy to your computer weekly or use UpdraftPlus (free version stores to Google Drive).
- ✅Test restore: Once per quarter, test restoring a backup to ensure it works.
4) Web Application Firewall (WAF)
- ✅Cloudflare (free tier): Blocks malicious traffic, DDoS protection, adds SSL.
- ✅Wordfence (free version): Monitor login attempts, block suspicious IPs.
- ✅Limit login attempts: After 5 failed attempts, lock out for 15 minutes.
5) HTTPS / SSL Certificate
- ✅SSL cert: Free via Let’s Encrypt (most hosts provide). Should show green lock in browser.
- ✅Redirect HTTP to HTTPS: Force all traffic through encrypted connection.
6) Monitor for Hacks
- ✅Wordfence alerts: Get notified of failed logins, plugin vulnerabilities, file changes.
- ✅Google Search Console: Monitor for malware warnings.
- ✅Regular scans: Run free Wordfence malware scan weekly.
7) User Roles & Permissions
- ✅Limit admin access: Only you should be admin. Others get Editor or Author roles.
- ✅Audit user activity: See who logged in, what they edited.
