What is Two-Factor Authentication? And Benefits Of Two-Factor Authentication

The internet is a dangerous place these days. You can’t walk down the street without being bombarded with people trying to get access to your personal information. It’s time to take some action and protect yourself online. Two-factor authentication has been around for years, but many still aren’t using it. This article will tell you everything you need to know about two-factor authentication so that you can start protecting yourself today!

Two-Factor Authentication protects against hackers who are targeting online accounts by adding an extra layer of security on top of passwords alone. Not everyone uses 2FA because they don’t understand what it is or how it works, which leaves them vulnerable in ways they may not even know exist. An extremely important privacy tool, 2FA is an additional layer of protection you want to have for all your accounts – especially the ones storing sensitive information like bank accounts or social media profiles.

What is two-factor authentication?

Two-factor authentication is a security measure that requires you to use an additional piece of information beyond your password. Typically this means that when you log in to a service, in addition to your password, you have to enter a code from an app or receive a text message before you can access the system. As such this type of authentication should provide extra security, but in practice, this is not always the case.

Why do We need two-factor authentication?

You might have heard of the term two-factor authentication (2FA) but you may still wonder why we and many other services recommend it. Even if you already use 2FA using a security key or application on your phone, you might not understand how vital they are for protecting your accounts even more.

The truth is that passwords alone are not enough to properly protect your accounts anymore. If you only use one password to protect all of your online accounts, sooner or later someone might steal it and be able to access them all.

Two Factor Authentication should defend against these types of attacks, but which kind is best? As mentioned earlier, there are several ways of implementing 2FA, but which one is the most secure?

Some services may offer 2FA using SMS or email code. The major problem with this method is that it doesn’t require any additional device to gain access to your account. This means that if an attacker manages to get hold of your password (e.g by using a keylogger), they can still gain access to your account even if you’re using 2FA.

As more and more users begin to understand the importance of 2FA, it is becoming more popular for services to implement TOTP (Time-based One-time Password Algorithm) or HOTP (HMAC-based One Time Password Algorithm). This method uses a mobile application or a security key to generate the codes and does not rely on an SMS/email provider.  Furthermore, they both use different algorithms and can be used with many services that do not offer 2FA via any other method.

 Benefits Of Two-Factor Authentication :

Two-factor authentication, also known as 2FA is a security measure that requires not one but two ways of identification to access your account.  The most common way of implementing this type of security measure is by verifying yourself through your phone number and password. When you login into the system with only the password to verify yourself, it is called single-factor authentication.

Two-factor authentication works in that you need your password to login into the system but then it requires another piece of information beyond just using your password to log in. This second piece of information is typically something they have (your phone) or something they are (fingerprint).

Why use two-factor authentication?

I’d like to address the main question here. Well, for starters it makes your account more secure than if you just use passwords to login into your system or devices that are connected to the internet. Your phone is something you always have with you and if someone gets access to your password they can’t use it without having your phone in their hands because even if they change the password they won’t be able to login into the system.

When implemented correctly two-factor authentication will increase security and help protect you from threats like identity theft, account hacking, and even physical threats like someone stealing your device (laptop, phone, etc). So if we put it this way: with single-factor authentication, a criminal would only need your password to log into your device and with two-factor authentication it would require them also to have access to your phone, making it harder for them to gain access.

If you use a lot of online accounts, even if some might not be as important as others, security is never too much when we live in an age where cyber crimes are becoming easier and easier due to the bad quality of programs or applications that are easier to hack into.

Having your account hacked can be way more damaging than you think. It’s not just your personal information that is at risk, but also any sensitive data you have stored on the account like documents, photos, etc. A hacker might change the password for your online banking system and set up a new password of their choice, they might steal your credit card information and empty your bank account.

This is why it’s important to always turn on two-factor authentication for all of the online accounts that support it when logging into your account. You can even set up things like Google Authenticator (app available on Android and iOS) to generate random security codes every 30 seconds and make it even harder for a hacker to gain access to your account.

Why should I use two-factor authentication?

Two-factor authentication is an extra layer of protection. It is the process of adding an extra check to verify your identity when logging in to websites or apps with passwords. To log in, you must know the password and have access to something that only you can use (e.g., a physical device). The two somethings are often referred to as “something you know” and “something you have”. The “something you have” is typically a mobile phone, but can be a FOB keychain, USB drive, or SMS token. In addition, companies that support two-factor authentication usually also enable additional security measures such as requiring strong passwords and enforcing strong password policies.

The exact process for two-factor authentication varies according to the service that you are using but usually involves entering your password as normal, then be prompted to enter a code sent by text message or generated on an app.

How to set up two-factor authentication on your account?

When you use a service, it is recommended that you enable two-factor authentication. This protects your account from being hacked. If someone has your password, there is nothing they can do to hack your account if they don’t have the 2nd code sent to your phone. Two-factor authentication is easy to set up.

  1. Go to your account settings here:
  2. Scroll down to the “Security” section
  3. In that section, click “Two-factor auth.”
  4. You’ll see a list of options for setting it up depending on what platform you’re using
  5. If you have your phone, follow the steps given to set up the authentication app for your account.

Once you’re done with that, you’ll get a code each time you log in to your account from an unrecognized device. You can still access your account like normal even if your phone is not present.

If you don’t have the two-factor authentication set up already, you can do so here.
