Two-Factor Authentication: Guide for a Website

22 June 2022 | admin

Two-factor authentication is the next level of security layer for a website. This system can help a website prevent cyberattacks. Therefore, many websites today have already been using two-factor authentication.

The Role of Two-Factor Authentication on a Website

Nowadays, more and more cyberattacks hit the company website. Some of them even gave big losses to the company. Because the website is hacked, it can make customers think that the security of the website is very minimal. This of course has an impact on decreasing the level of trust and reputation of the company from the customers’ perspective. 

Not only companies, but customers can also get the impact by the hacking, for example, their personal information can be exposed. The theft of personal data can provide financial losses to customers, such as credit card burglary.

Therefore, a website needs to provide double protection by adding an extra layer of security, namely two-factor authentication. Examples of platforms that implement two-step authentication are WhatsApp, Facebook, Instagram, and Gmail. The use of two-step authentication can prevent intruders from entering the accounts even if they have the user's password.

Currently, the use of complex passwords will not be enough to secure accounts from hacker attacks. Because there are various ways that hackers can do to break into user accounts. Starting from brute force to phishing.

In a CMS like WordPress, two-step authentication is also important to prevent your WordPress account from being compromised by hackers.

How Does a Two Factor Authentication Work on a Website?

The way two-step authentication works is generally the same as follows:

  1. The password will be authenticated by the authentication server.
  2. If the password is correct, the authentication server will release a code to the user’s second device.
  3. The User should insert the code from the second device. 

In short, two-step authentication will perform a second verification after the user enters the password. Usually, there is some kind of information that becomes the second verification. For example, in Gmail, users are given several options such as:

  • Connect the Gmail account to the user’s smartphone, so that anyone who logs into the Gmail account must click on the word 'YES' that appears on the smartphone to confirm. 
  • Use of the verification code sent via SMS.

While on Instagram, the use of two-step authentication is by entering a code sent via SMS or WhatsApp using a PIN.

The use of two-step authentication can also provide information to users if someone has compromised their account. So that users can perform security by changing the password.

If your website already has two-factor authentication, then the level of customer trust in the company will increase. Because customers will trust and believe if everything they do when accessing the company's website is safe from hackers
