How to Add Two-Factor Authentication for WordPress

Best Two-Factor Authentication WordPress Plugins


Did you know that you can add two-factor authentication to WordPress? If you’re not sure you would want to add two-factor authentication to you WordPress website consider this – how many accounts across the internet do you possess? All of them password protected? How many share the same password? If an unwanted visitor gains entry into one account, he may most likely gain entry into others. You will make it easier for him if you use easy to guess passwords or use public networks. Is it the name of your pet dog? Your birthday? Have you written down that password in a diary?

Everyday, bots attack thousands of WordPress websites and expose their visitors to malware. A website that is bot infested gets de-listed by search engines, hosting service providers may block access to the website. This means that the websites begin to lose traffic. All your hard work is reduced to nought.

What is Two-Factor Authentication?

Passwords can be broken, especially by brute force attacks. This is where it helps to add another layer of security, beyond a simple password. Two-factor authentication is one way of doing this. In fact, many popular websites (e.g., Facebook, Gmail, PayPal, etc) use two-factor authentication to minimize security breaches in case an attacker steals user credentials.

So what exactly is two step or two-factor authentication (2FA for short)? You could call having to enter a captcha as a two-factor authentication in it’s simplest form. Or you may be required to enter an additional PIN number. Some websites need you to identify a pattern before you can login. What two-factor authentication essentially means is that users will have to confirm their identity beyond passwords using some device that they have in their possession.

The technology does not replace the password; it adds an extra step that only you, the rightful admin, can access. In this process, you would login just as usual, but after that you need to enter a code that will be sent to your mobile or any other device. 2FA offers an additional layer of security, so that even if your password is overcome, the hacker cannot access your website without an additional piece of code. This code is sent to your registered phone number, email, app etc. It is commonly referred to as One Time Password or OTP and only upon entering this is access gained to the website.

Methods to receive the code used for Verification?

Before you begin to use the the Two-Factor Authentication on your system, it makes sense to understand how the second step works, so that you can pick the one best suited for you. The code that you input during the verification can be received by you in any one of the following ways,

Email Services: When you try to login, the code is sent to your email.
SMS: Sent to your mobile phone.
App Generated Codes: Apps like Google Authenticator will automatically generate a new code at very short time intervals. The code that is currently generated when you are logging in will have to be entered. The app may take a bit of setting up.
USB Tokens: You will simply have to insert a token into your USB port (and maybe enter a token password). Nothing further. This is a very safe method, as there is no way in which the authentication can be intercepted. But it has the disadvantage of not working with mobiles, as it needs to be inserted into a USB port.

The first two methods will need internet or cellular connectivity for receiving the code, while the last two are not dependent on connectivity.

All services will not offer all the options and you must choose what is best for you. Some services may offer more than one option, in which case you will have a fall back option. Often, when you are setting up the authentication, you will be provided with Recovery Codes, which you should note down and keep safely.

In today’s post, we share our picks of the best two-factor authentication WordPress plugins to bolster security on your login page. The 2FA WordPress plugins in the following section are all easy to configure. They ship with adequate installation instructions and documentation, so we don’t expect any problems.
