Why 2FA is Non-Negotiable
80% of WordPress hacks involve compromised credentials. Even strong passwords fall to phishing. 2FA blocks attackers even with valid passwords — it’s the most effective defense against account takeover.
2FA Methods
Authenticator Apps (Best)
Google Authenticator, Authy, Microsoft Authenticator. Time-based one-time passwords (TOTP). Works offline. No SMS vulnerabilities. Free.
Email Codes
Backup method. Send 6-digit code to email. Simple but slower.
SMS (Legacy)
Phone text codes. Vulnerable to SIM hijacking. Avoid as primary but useful as backup.
Hardware Keys (Premium)
YubiKey, Google Titan. Phishing-proof. Best for high-security accounts.
WordPress 2FA Plugins
Wordfence Security (Free Tier)
Built-in 2FA with email and authenticator support. Integrates with firewall. Most popular choice.
Two Factor Authentication by Google
Official, lightweight. Authenticator-only. Good for minimal overhead.
Duo Security
Enterprise option. Phone prompt + push notifications. Beautiful UX.
