In light of the current scenario, it is not too hard to understand the rate at which cybercrimes are increasing day by day across the globe. It is therefore of utmost importance these days to take proper care of our online presence and enable two factor authentication on our devices. Different organizations adopt varied methodologies to eradicate and prevent cybercrimes. Two factor authentication or 2fa can be considered as an extra layer that is often used by various organizations as well as various individuals each day to make sure that their system is free from all kinds of external attacks.

Cyber hacking has evolved to be one of the major concerns these days and two factor authentication can go a long way in preventing online data from numerous external attacks.

There is a huge tendency among people to rely only on passwords to protect data privacy which is why the rate of cybercrime has been increasing daily. It is extremely important to be aware of 2fa meaning, what is 2fa, and the benefits of using proper two-step verification methods, and how one can ensure data privacy.

In this article let us look at:

1) What is Two Factor Authentication/ What is Two-Way Authentication?

The first step is to understand what is 2 step authentication. A two-step verification basically makes sure that those who try and access private and confidential data are those that they claim to be. 2 step verification, therefore, ensures data privacy and keeps it free from different kinds of external attacks. 2-factor authentication takes place in various ways. Whenever someone tries to access a particular account or profile online, they are subjected to a few questions regarding specifications that have already been set by the original user. This way, it makes sure no one except for the original user gets access to these apps.

Therefore, the purpose of setting two factor authentication is to make sure that the account remains safe even when you forget your password or lose your gadget somewhere. No one else will be able to access your data due to 2fa authentication settings which will keep it free from all kinds of unethical and illegal activities.

2) Common Types of 2FA

The most known and used types of two-step authentication or 2fa is basically a set of questions that are set by the original user. For instance, the questions can be focused on something you know or something you have or something you are, or perhaps something you like. A 2fa authentication basically prevents users from getting access by only putting the password. They are asked to answer a few more questions based on various details provided by the user initially and then they get access to these apps. To ensure accurate implication of this security route, it is important to know what is 2-factor authentication or what is two-step verification.

Sometimes passwords are simply not enough to protect data from external attacks. Therefore, two-step verification can be extremely helpful in doing so in our day to day life. Multiple apps do not ask you to set further questions for extra protection and needless to mention, the accounts on these applications are the apps that are highly likely to get hacked from time to time. 

Having a two-way authentication makes it easier for you to have your data protected from unwanted external illegal activities daily. Various two factor authentication methods are used these days by organizations. Some of the most common 2-factor authentication examples are:

1. Hardware Tokens for 2 step authentication: It is one of the oldest forms of 2-way authentication which is widely popular and is used by various organizations across the globe. This is a second-factor authentication method that aims at producing new numeric codes every thirty seconds. Whenever someone tries to access a particular account, they are asked to put the displayed dual-factor authentication code to be able to get access to that particular account.

In some cases, the 2fa is automatically transferred by the system so that the user does not have to put it again. This only happens when the computer is connected with USB, otherwise, it does not work.

2. Text Message and Voice-based two factor authentication: This dual-factor authentication method focuses on protecting data by remaining connected with the user’s mobile phone. After they enter their password, they receive an OTP aka one-time password which is expected to be entered by the user on the site of the app they are trying to access. This way their data is protected from external attacks. 

It is one of the most common two factor authentication 2fa methods which is widely used by thousands and millions of users across the world.

3. Software tokens for 2fa authentication: This is also one of the major two factor authentication types. To follow this method, users are expected to install a free 2fa app first on their phones. This app then generates codes that they are supposed to enter while entering a particular app. This code lasts for one minute and upon successfully entering the code they are granted access to the app. Such newer means of authentication are on a rise with an increase in the security norms, therefore 2-factor authentication meaning is essential to be understood by every internet user these days.

4. Push notification for second-factor authentication: Instead of fully depending on passwords and external apps, certain websites have the function to send push notification these days on the user’s phone immediately after they try accessing a particular app from their device. They can simply view the details of the code and more and then they can go on entering the app without any issue whatsoever.

These are some of the most common two factor authentication methods that are widely used by people and organizations across the globe. However, apart from these methods, there are other 2fa authentication methods as well which are extremely helpful in protecting data privacy.

3) Other Forms of Two Factor Authentication

One of the other major two factor authentication methods is the Biometric 2fa which aims at protecting data privacy by following various methods like using token and codes to ensure the privacy of data. Some of the recent developments in this field have ensured a person’s identity is verified before they can access several apps. These two-step authentication methods verify identity by approving the user’s fingerprint, voice tone, facial recognition, and more. Typing patterns are also verified by some of the complex two-step authentication methods. Pulse, retina patterns, voice modulations have also become part of the verification process these days.

However, the first and foremost step that should be taken in order to increase the usage rate of two factor authentication methods is to spread awareness among people to make them understand why it is so necessary to use double factor authentication methods and what the drawbacks of passwords are, how they fail to protect our data privacy from time to time and why it is never enough to depend on a single password to protect sensitive data.

This way, the awareness will increase the importance of two-factor verification and more and more individuals will eventually start using this to ensure data privacy.
