Are you aware that integrating two-factor authentication into your WordPress site is a wise move? If you’re uncertain about adding this extra layer of security, consider the multitude of accounts you own across the internet.

Are they all safeguarded by passwords? How many of them share the same password? If an unauthorized user gains access to one account, they could potentially infiltrate others, especially if you use easily guessable passwords or connect to public networks.

Is your password something as simple as your pet’s name or your birthday? Have you noted it down in a diary?

Every day, numerous bots launch attacks on thousands of WordPress websites, putting their visitors at risk of malware exposure. A website inundated with bots may face consequences such as being delisted by search engines, and hosting service providers might block access. Consequently, the site begins to lose traffic, rendering all your hard work futile.

What is Two-Factor Authentication?

Passwords are susceptible to being compromised, particularly through brute force attacks. To enhance security beyond a simple password, incorporating an additional layer of protection is crucial. Two-factor authentication (2FA) serves this purpose and is widely adopted by popular websites like Facebook, Gmail, PayPal, among others, to mitigate security risks in case of stolen user credentials.

So, what exactly is two-factor authentication, also known as two-step authentication (2SA)? In its simplest form, entering a captcha can be considered a basic type of two-factor authentication. Alternatively, users might be prompted to input an additional PIN number or recognize a specific pattern before gaining login access. Essentially, two-factor authentication requires users to verify their identity beyond passwords using a device they possess.

This technology doesn’t replace the password but adds an extra step that only the rightful administrator can navigate. Following the usual login process, users are then required to enter a code sent to their mobile device or another registered device. 2FA provides an additional layer of security, ensuring that even if a password is compromised, the hacker cannot access the website without the corresponding additional code.

This code, commonly known as a One Time Password (OTP), is sent to a registered phone number, email, app, etc., and access to the website is granted only upon entering it.

Ways to obtain the verification code?

Before initiating the use of Two-Factor Authentication on your system, it’s essential to comprehend how the second step operates so that you can choose the method most suitable for you. The verification code, entered during the authentication process, can be received through any of the following means:

  • Email Services: The code is sent to your email when attempting to log in.
  • SMS: Sent to your mobile phone.
  • App Generated Codes: Apps like Google Authenticator automatically generate a new code at short intervals. The currently generated code during login must be entered. The app requires some initial setup.
  • USB Tokens: Insert a token into your USB port (possibly entering a token password). This method is highly secure, as authentication cannot be intercepted. However, it is not compatible with mobiles, as it necessitates a USB port.

The first two methods require internet or cellular connectivity for code reception, while the last two are independent of connectivity.

Not all services offer all options, so you must choose what suits you best. Some services may provide multiple options, offering a fallback alternative. When setting up authentication, you are often provided with Recovery Codes, which should be noted down and securely kept.

In this post, we present our recommendations for the best Two-Factor Authentication WordPress plugins to enhance security on your login page. The plugins discussed in the following section are user-friendly, accompanied by clear installation instructions and documentation.

Any potential issues are not anticipated. Feel free to share your preferred 2FA WordPress plugins or security concerns at the end. Without further delay, let’s delve into the plugins.
