WordPress two factor authentication is a must-add security layer for your site, requiring both something you know, your password and something you have, like your phone. Accounts with multi-factor authentication enabled are significantly less likely to be compromised. Before diving in, run through our comprehensive WordPress security checklist to cover all your bases.

Understanding Two Factor Authentication

What Two Factor Means

Two factor authentication adds a second step to your login process. After entering your password, you’ll verify with a one-time code, push notification, or hardware key. This simple extra step makes stolen passwords far less useful to attackers.

Types of Authentication Factors

Authentication methods fall into three main categories:

  • Something You Know, like a password or PIN
  • Something You Have, such as a smartphone app or hardware token
  • Something You Are, for example a fingerprint or facial scan

Most WordPress solutions use the first two factors, since biometrics require specialized hardware.

Benefits of Two Factor Authentication

Prevent Unauthorized Access

With just a password, hackers only need to guess or phish your credentials to break in. Adding a second step locks out most automated attacks and credential stuffing.

Meeting Compliance Requirements

In industries like healthcare and finance, regulations often mandate multi-factor security to protect sensitive data. For standard WordPress sites, two step verification helps you stay ahead of compliance trends.

Selecting a 2FA Plugin

Key Features to Consider

When choosing a plugin, look for:

  • Support for Time-Based One-Time Passwords (TOTP) apps like Google Authenticator
  • SMS or email backup methods in case your device is offline
  • Hardware key (U2F) options for extra security
  • Easy user setup and clear admin controls

How to Enable Two Factor Authentication in WordPress

Install and Activate Plugin

f2a plugin

  1. In your dashboard, go to Plugins > Add New.
  2. Search for your chosen 2FA plugin name.
  3. Click Install Now, then Activate.

Configure Authenticator App

  1. Navigate to Users > Your Profile.
  2. Find the 2FA settings section and choose Authenticator App.
  3. Scan the QR code with your phone’s authentication app.
  4. Enter the one-time code to confirm.

Save Emergency Backup Codes

Once setup is complete, most plugins give you backup codes. Print or download these but do not store them on the same device. They rescue you if you lose access to your phone.

Troubleshoot 2FA Issues

Lost Authenticator Device

If you can’t access your authenticator app, use a backup code first. Can’t find your backup codes?

Using Backup Codes

Backup codes work one time only. Cross off each code as you use it. Running low? Generate a new set in your plugin settings but remember this invalidates old codes.

Reset or Disable 2FA

If you’re completely locked out, reach out to your site admin or hosting support. They can disable the plugin via FTP or database and guide you through a fresh setup.

Maintain Your 2FA Setup

Update Your Authentication Methods

When you get a new phone, transfer your authenticator app accounts before wiping the old device. Many apps offer built-in export/import features.

Revoke Old Devices

Periodically check your 2FA plugin settings and remove any devices you no longer use. This shrinks your attack surface.

Review User Access Logs

Scan your WordPress login logs for repeated failed attempts or suspicious login patterns. You might spot unauthorized access before it becomes a breach.

Key Takeaways and Actions

  • Add a second verification step to keep hackers out.
  • Choose a 2FA plugin that matches your needs and budget.
  • Always save backup codes somewhere safe.
  • Troubleshoot lockout issues with recovery codes or support assistance.
  • Keep your device list and backup codes up to date.
