6 Reasons Why Two Factor Authentication is Important

by Uneeb Khan

Two-factor authentication (also known as 2FA) is an additional layer of security that almost all services offer today. It’s designed to stop hackers from getting into your account even if they know your password. 

Hackers would usually try to guess your password or log in with your email address and a bogus password, which is why almost every service has a way to send you a password reset link or code after you log in. 2FA makes it much harder for hackers to break into your account.  

It requires something you know (your password) and something you have (a code from an app on your phone or something like Google Authenticator). If most services provide the only security measure is a username and password verification, then anyone can hack into it. That is why you need the best authentication online solution for your accounts. 

 However, when two-factor authentication comes into play, hackers will have no chance of getting in, even if they know the username and password. Here are seven reasons why two-factor authentication is essential: 

1. It Protects the Information You Store in Your Account 

Two-factor authentication is a secondary layer of security that can be used in conjunction with a username and password. This additional layer ensures that only authorized users can access a particular account. 

It also protects the account from unauthorized access, especially if a hacker or someone with malicious intent manages to get a hold of your username and password. For example, if a hacker gets your username and password, they can easily log in to your account and begin taking actions you don’t intend, such as deleting your data or sending spam emails from your account. 

 But if two-factor authentication is enabled, the hacker won’t be able to log in even if they have your username and password because they won’t have the second authentication factor. 

2. It Makes it Harder for Hackers to Break in 

The most crucial goal of any security measure is to make it harder for would-be hackers to break in. The best way to do this is to make hacking into an account as complicated as possible. 

Two-factor authentication is a great way to do this. While getting into an account with just a username and password is easier, it’s much harder to do so when an authentication code is also required. Two-factor authentication can differentiate between your account remaining secure and being hacked. 

3. It Helps Fight Phishing and Malware Attacks 

You could still fall victim to a phishing attack even if you use a strong password. Phishing is when someone tries to trick you into giving them your username and password by pretending to be a legitimate service, like your online banking site.  

For example, a hacker might send you an email pretending to be your bank and tell you that you need to update your details. The email could even look like it came from your bank. If you click on the link in the email and log in to your bank account, you’ve just given the hacker your username and password.  

With two-factor authentication enabled, however, the hacker won’t be able to log in to your account even if they have your username and password because they won’t have the second authentication factor. 

4. Makes it Harder to Commit Identity Fraud 

Two-factor authentication makes it harder for someone to steal your identity and commit identity fraud. This is especially important if you have been the victim of a data breach. You may not know that your information has been stolen until you get a call from a debt collector or discover that your health insurance has been canceled. 

 Two-factor authentication can help reduce the risk of this happening to you. When you enable two-factor authentication, you’ll be prompted to provide a second form of identification whenever you log in to a support service. This means you’ll have to provide more than just your username and password, making it much harder for someone to steal your identity. 

5. Helps Recover Your Account if You Lose Your Password 

It’s scary to think that if you lose your password, then you’ve lost access to your account. But it does happen, and two-factor authentication is a great way to recover your account if this happens to you.  

Some services will let you enable two-factor authentication without entering an authentication code every time you log in. If you lose your password, you can ask the service to reset it, and they’ll send a message to the app on your phone with a new one you can log in with. It’s like having a secret decoder ring or magic key that only you know. 

6. Ensures Only You Can Have Access to Your Account 

If someone knows your password, they have access to your account. But with two-factor authentication enabled, this isn’t necessarily true. If someone knows your password and they have your phone, they can try to log in to your account. 

But if two-factor authentication is enabled, they won’t be able to log in even with your phone because they won’t have the second authentication factor.  


In today’s digital world, users are more frequently prone to cyberattacks than ever. It is more important than ever for users to take measures to protect their data and accounts. Users may create passwords with complex characters, words, and phrases that are not easy for others to guess. However, hackers continue to find new ways to breach user accounts. That is why two-factor authentication (or “2FA”) has become so popular recently. If you haven’t yet implemented a two-factor authentication system on your personal or business accounts, then consider the benefits mentioned above.
