Boost WordPress Security By Adding Two-Factor Authentication

Did you know that there are thousands of WordPress blogs and websites hacked every yearand the number of hacked WordPress sites is expected to increase even more in the future? Hackers are everywhere and they are getting “better” at hacking, so your site can be attacked at any time.

The question is: While there is always patch for vulnerability now, is it best to use static passwords?

The answer is certainly no. Two-factor authentication can solve this problem. This service will try to verify that you reallyare the person you say you are, and not just accept the password you give.

This blog post can give you an overview of two-factor authentication, and then how you can apply it to your WordPress site.

Who are you, two-factor authentication?

It used to be that having a strong password policy was enough to prevent hackers from accessing to your site. However, as security continues to evolve, it is clear that a strong password is not enough. A simple and effective way of improving the way you secure your WordPress site accounts is by using a method called two-factor authentication.
Two-factor authentication is a method where your users are required to log in with two “factors”: a password or a code from a device that they have, maybe their mobile phone. Two-factor authentication is one of the best things you can do to make sure your accounts don’t get hacked.

WordPress is not the only one applying two-factor authentication; a lot of sites have recently implemented it, including many of our favorite services: Google, Facebook, LinkedIn, Twitter, Dropbox, etc.

It’s clear that two-factor authentication is well known, right? You need to have a deep awareness of its necessity to boost your WordPress site security.

Do I need to add two-factor authentication to my WordPress site?

Google’s spam guru, Matt Cutts, has commented about the importance of two-factor authentication:

Two-factor authentication is a simple feature that asks for more than just your password. It requires both “something you know” (like a password) and “something you have” (like your phone)It’s a lot more secure than a password and keeps unwanted snoopers out of your online accounts.

Do you think you need two-factor authentication for your WordPress site? Believe me; you will be persuaded to do it right away

  • Using your username and password along with some personal information that only you have access to makes it harder for potential intruders to gain access and steal your personal data or identity.
  • Moreover, two-factor authentication can help to protect your site from brute force attacks. Brute force attacks work by systematically checking all possiblekeysorpasswordsuntil a valid one is found.

Two-factor authentication can help you avoid this problem through its password-verifying process.

Dear two-factor authentication, how do you work?

Remembering many different account passwords from your WordPress account to gmail, bank, or even your favorite forum account is always a challenge, right? So I’m sure that many of you will use the same account password for many sites. This means that your accounts can be hacked in a domino effect.

Well, two-step verification is just the solution for that. Even if the hacker knows your WordPress username and password, they will not be able to access your site. Because your site is directly connected with your mobile device, you are the only person who should have access to this to get a unique code for each login.

The unique code often expires in a short amount of time for security purposes too.

Recommended two-factor authentication plugins

Google Authenticator


The Google Authenticator plugin for WordPress gives you two-factor authentication using the Google Authenticator app for Android, iPhone, and Blackberry.

If you are security aware, you may already have the Google Authenticator app installed on your smartphone, using it for two-factor authentication on your WordPress site.

You will need to download and install Google Authenticator both on your WordPress site and your smart phone to ensure you login to your site by opening the app on your phone and entering the provided authenticator key.



Cleft is a mobile app that replaces usernames and passwords with your smartphone.

After installing and activating the Cleft plugin on your WordPress site, you create a Cleft profile on your phone too. Cleft uses that profile to generate a new digital signature every time you log. Then you sync Cleft Wave to identify yourself on your WordPress login.

Duo Two-Factor Authentication


Duo Security provides two-factor authentication as a service to protect against account takeover and data theft. Rather than relying on a password alone, Duo’s authentication service adds a second layer of security to your WordPress accounts. Duo enables your admins or users to verify their identities using something they have – like their mobile phone or a hardware token – which provides strong authentication and dramatically enhances account security.

Duo is easy to setup and use. With Duo there’s no extra hardware or complicated software to install, just install this plugin and sign up for Duo’s service. Then you can set which user roles you want to enable two-factor authentication for – admins, editors, authors, contributors, and/or subscribers – without setting up user accounts, directory synchronization, servers, or hardware.

The only problem with this plugin is you only have a limited number of people who can use the website with the free version.

    Two-step authentication can also prevent legitimate log ins. If a user forgets their phone at home and has two-step authentication enabled, then they won’t be able to access their account.
