WordPress security improvement: adding 2-factor authentication

Another great way to improve the overall security of your WordPress website, is by adding two-factor authentication to your WordPress security measures. It improves your security since it requires 2 seperate elements to be entered before a user will be granted access and is, by default, a better solution than just using a username and password combination to log in. Two-factor authentication usually requires you to enter both a pincode/token of some sort and validate another element before access is granted.

How this improves your WordPress security

Using 2-factor authentication helps to effectively protect your website against following attacks and vulnerabilities:

  • Brute-forcing attacks
  • Weak passwords set by the end-user
  • Passwords that have be intercepted via man-in-the-middle attacks

But that’s enough theoretical chitchat already. Let’s go over the best options available today:
