Why 2-Factor Authentication is a must for Apps and Websites

Why2-Factor Authentication is a must for Apps and Websites

We all know the dangers of the online world. Previously, other than passwords, no technology existed that would help provide us with an additional layer of security. Online security has become a significant concern in today's world, where everything related to our lives has become online. As a result, every app and website must maintain their customer's trust and employ security measures that will be difficult to compromise. That's where the 2-factor authentication comes into play.

It has become a prominent technology for enhancing online safety on several platforms. Of course, you may already use it on some of your apps or digital platforms. However, today let's get to know in detail about it.

What is 2-factor authentication?

Two-factor verification is a dual security process in which users must provide two different authentication factors to identify themselves. Two-factor authentication has become very useful and essential in today's world. It protects both the identity and credentials of the user. Furthermore, it protects the resources and information the user is trying to safeguard. Today most apps rely on providing a password as the first factor and a biometric token as the second factor.

Why apps and websites are inclining toward using 2-factor authentication?

Today scammers can obtain your personal information. Hackers can quickly figure out the passwords, and this will cause a security breach. This is why apps and several websites arm themselves with two-factor authentication to fight such advanced scamming techniques. Two-factor verification is essential to web security because it immediately neutralizes the risks associated with compromised passwords. Today two-factor Authentication is used in a broad range of areas, from Banking, social media apps, e-commerce sites, and many others. It enables businesses and public institutions to be more efficient and allows employees to perform tasks with far fewer security concerns.

A website can be on the receiving end of phishing and spamming. Two-factor verification is essential in securing a website by blocking some application-based attacks.

How does two-factor authentication work?

Depending on the website's or app's specific needs, a company can implement the two-factor verification as a required step for every login attempt or just those that the system has flagged. For example, many Banks will only require users to complete a two-step verification if they log in from another number.

This is how the authentication process looks

  • To request access to your account, a person must arrive at the website's login page and enter their username and password.
  • If the app has enabled a two-factor verification, the system will decide whether they need to carry out the additional verification step to ensure they are not hackers.
  • The person who registered the phone number when they established the account will receive a text message containing a code. During this time, a second login screen will appear and ask the person to enter the code.
  • Once the person enters the passcode, the system will check whether the code the person puts in matches the one supplied.  
  • The person will now quickly and safely be able to access their account if there is a match.

Elements of two-factor Authentication

Two-factor authentication is a part of multi-factor verification. But one needs to remember that utilizing two elements from the same class will not constitute two-factor authentication. Usernames and passwords are certainly not the most secure authentication method for apps and websites. Password-based authentication has many drawbacks. The more critical problem is that it takes skill, knowledge, and care to generate and remember secure passwords.

Most people lack such knowledge even today. In addition, passwords need to be heavily protected from various insider risks. For example, passwords are vulnerable to external dangers like hackers. With time, any experienced hacker can hack a weak password and thus have access to your private information. Nevertheless, passwords have remained the most common step of two-step verification, as they require low expenses and have a touch of familiarity and ease of implementation.

Multiple questions can also provide more security. A question that only the user knows the answer to can be asked. This will lower the chances of an unknown outsider hacking into the app or the website. Today biometric verifications have also become very popular. A biometric scan is a way of verifying the user's identity by using a piece of themselves. A fingerprint scan is the most common form of biometric identification. It has also been incorporated into many apps. Other advanced biometric security measurements include voice identification, iris scan, and many others.

Types of two-factor Authentication

It is without a doubt that two-factor authentication is essential today, in a world where each piece of information is susceptible to falling into the wrong hands. Therefore, it is indispensable to take proper protection. Two-factor verification is the best choice for such cases. Several devices, apps, and websites have implemented two-factor verification. Two-factor authentication is divided into two categories. The first is the tokens that are given to users when logging in.

The second is the infrastructure or software that authenticates access for the users who are entering their tokens correctly. Authentication tokens may be physical or incorporated in the mobile, desktop, app, or website that generates the PIN code for authentication. These authentication codes are one-time passwords that only work for a short period. An essential aspect of two-factor authentication is ensuring the user is given access to all the resources the person is approved for. This links the authentication system with the app or website's authentication data.

Importance of two-factor verification

The 2-factor verification comes with immense benefits such as;

Provides an extra layer of security

In recent years we have witnessed a rise in cyber crimes, and many people are directly affected by them. Due to the rising sophistication of cybercrime activities, different companies are arming their apps and websites to better deal with the problem. A cybercrime breach will directly affect the customers who have trusted the company with their personal information. Two-factor authentication is the perfect solution to the problem. It offers better security protection and protects the personal identities of the clients. When someone tries to log into your account, it will immediately take them to a screen asking for a code. This makes hacking more difficult than before.

Helps strengthen brand reputation

As said before, it is the responsibility of every brand to make sure their employees and customers are well protected from phishing attacks. Implementing a two-factor authentication builds brand reputation. Customers will be more willing to download apps that are better protected. It will give them peace knowing a two-factor authentication is implemented. Even in the case of websites, potential customers will be unwilling to visit a site that is poorly protected.

Is two-factor authentication truly secure?

Today, people are more aware of cyber threats and the consequences of not protecting themselves online. Two-factor authentication is the latest technology that helps protects us against any attacks. Most websites and app shave adopted it as well. But is two-factor authentication truly secure? Two-factor authentication can also be susceptible to cyber security failures like any system. In recent years there have been cases where a massive breach occurred even after the setting up of two-factor verification. Therefore, people using apps and websites that require two-factor authentication must be careful while entering their data. Two-factor authentication is undoubtedly better than other available technologies. It most certainly provides an extra layer of protection. But this does not mean it is 100% foolproof. Many problems can be avoided if we are careful while entering our data on apps and websites.


Technology continues to evolve with each passing day. With time more focus is given to the individual user. As a result, the authentication security process will only become more complex and critical. It is without a doubt that apps and websites should incorporate a two-factor authentication. The mobile devices we possess will become a core aspect of authentication, with two-factor authentication providing for more excellent protection and authentication intelligence.
