Have you ever faced a password breach? We all had to recover our emails or other application accounts only because of password hacking.

Now, the password seems to be the secure thing to do, but it fails us when any person with a sneaky mind hacks into our accounts and steals or destroys our data. This counts as the most dreadful cybersecurity threat. Considering these scenarios, various online platforms and applications offer 2-factor authentication methods.

But do we know everything about it? If yes, it would be great for you. We are only here to solve your query if you are curious to know a bit more about it.

Why passwords aren’t enough

Why should I use 2FA? This can be a concerning question.

You might also wonder; A password is sufficient to secure online accounts, right? Is your password secure enough, first of all? Hackers can quickly break weak passwords using brute force attacks or “password spraying,” which involves testing a list of the most popular passwords. Therefore, you should refrain from employing anything too obvious, such as dictionary words.

Even if you do have a password that is extremely difficult to crack, there are still several cunning ways for hackers to do so:

  • Data breach
  • Phishing
  • Spyware

Everything you must know about 2-factor authentication

Today, 2FA is frequently used in online banking, social media, and e-commerce websites as a way to strengthen access controls to a web application’s more sensitive portions.

Additionally, two-factor authentication makes it possible for businesses and government agencies to operate more effectively and productively by letting workers work remotely with fewer security worries.

Common Types of 2FA

There is a strong likelihood that a website you use will be hacked someday if all that is needed to access it is a password and there is no 2FA available. Despite this, not all 2FA is the same. Various forms of two-factor authentication are in use today; while some may be more powerful or intricate than others, all provide better security than passwords alone.

Let’s examine the most typical 2FA implementations.

●    Hardware Tokens for 2FA

Hardware tokens, possibly the earliest type of 2FA, are small, like a key fob, and they generate a new numeric code every 30 seconds. When a user attempts to access an account, they quickly scan their device and type the 2FA code that appears in the website or mobile app again. Other iterations of hardware tokens transmit the 2FA code automatically when connected to a computer’s USB port.

●    SMS Text-Message and Voice-based 2FA

A user’s phone is directly involved in 2FA. The website asks the user for a login and password before sending a one-time passcode (OTP) through text message.

●    Software Tokens for 2FA

The most widely used method of two-factor authentication (and a preferred substitute for SMS and voice) makes use of a time-based, one-time passcode that is generated by software (also known as TOTP, or “soft-token”).

●    Push Notification for 2FA

Websites and applications can now give users a push message to alert them that an authentication attempt is being made rather than relying on the receipt and submission of a 2FA token. The device owner only needs to read the specifics to allow or refuse access with a single tap. There is no need to enter codes or engage in any more interaction because it is passwordless authentication.

Need of 2FA for Web application security

In order to secure your website, two-factor authentication can help by thwarting a variety of application-based assaults.

In order to guess a user’s credentials, these include brute force and dictionary attacks, in which the perpetrators utilize automated software to produce a huge number of username/password combinations.

When 2FA is enabled, these attacks fail because, even if attackers are successful in learning a user’s password, they are still missing the second piece of identity required to access the application.

In addition, social engineering attacks like phishing and spear phishing, which try to trick a user into disclosing sensitive information like their username and password, can be thwarted by applications using two-factor authentication.

A perpetrator would still need the additional form of identity demanded by a 2FA solution, even in the case of a successful attack.

Why any enterprise needs Two-factor authentication

Corporate settings are more likely than public services to embrace 2FA. Many businesses that use remote workers have heavily embraced 2FA. The RSA SecurID is the most popular and established 2FA technique for businesses.

Probably, it has been around for a while and is available as a hardware dongle that looks like a USB stick and has a screen that displays the code or can be installed as an app.

Some competitors have started concentrating on Single Sign On (SSO), allowing users to access numerous third-party services after only logging in once. SSO is used extensively by many businesses, and it is growing in popularity too.

2FA – Secure or hackable?

Even though 2FA is significantly more secure than a password alone, it is not completely infallible; regrettably, nothing online is. However, cyber threats are not for specific individuals. Instead, they go at vulnerable people with lax security. And if one individual is challenging to get along with, they’ll typically move on to someone who is. Due to this, 2FA almost always keeps you secure.

However, if a hacker has a lot of time and resources at their disposal and is deliberately targeting you, they might find a way to get in. How? A hacker could be able to infect your computer with software that duplicates the Google Authenticator code. But even so, the hacker would only have a few seconds to capture and enter the code before you obtain access.

Alternatively, a cunning cybercriminal may opt for a social engineering hack that persuades a mobile operator to give them control of your phone number. The second piece of information for verification, an SMS code, is then given to them rather than you.


●    How does two-factor authentication increase the security of your account?

In order to improve your attempt at signing in, add a confirmation step. Even if the user knows your password, utilizing the SMS example will prevent them from accessing your account because a verification SMS will be sent to their phone number.

If someone tries to enter your account after you click “submit,” a page demanding a code will display. The specified mobile phone number received this code by SMS.

Some apps allow you to respond to push notifications from other devices currently associated with that account. There are many ways to implement 2FA.

●    What happens if I don’t have two-factor authentication?

If you’ve forgotten your password or don’t have a second step. Important: An additional step is needed with 2-Step Verification to demonstrate account ownership. Due to the enhanced security, it may take 3-5 business days to verify that you are the intended user. To retrieve your account, follow the instructions.

●    What is an example of 2-factor authentication?

Two-step authentication involves using two knowledge factors: a password and a PIN. Two-factor authentication involves using two distinct factors: a password and a one-time passcode provided to a cell phone through SMS.

Bottom line

If you are always trying to doge the rain with a hand on your head, you need to look for better security ways. Access control with smooth action and proper strategy of 2FA can make a huge difference. So, be it your enterprise or an individual account, you must learn how to protect it from cyber threats of any kind.
