There are many who will say Two-Factor Authentication is not worth the hassle, but we beg to differ - here's why you should use it! Antivirus Compared - What is Two-Factor Authentication and Why Should You Use it

Everyone knows that the internet isn’t the safest place to share your data; thousands of hackers and companies are trying to get a hold of your information every single moment you spend browsing. No password is safe these days, but two-factor authentication arrived to add an extra layer of security during your logins.

What is it?


Two-factor authentication serves as a secondary security measure for login into different accounts on the internet; bank accounts, email, social media, web-based wallets, pretty much every robust web platform features it. It usually works by asking you more information before letting you in right after you input your regular password when logging into different sites.

The main purpose of this process is to deter hackers from accessing sensitive information, greatly reducing the risk of fraud in the process. Although it can’t keep all hackers away, like any other cybersecurity measure, it definitely reduces the threat.

What’s the Required Information?


If you already have a password, what would the platform ask you then? Well, there are several ways to make sure you’re the one logging into your account. There are three main ways to do this.

Your Secret Information
We could be talking about the typical questions set beforehand for you to answer when a two-factor authentication window appears in front of you, but there are also other options available including a PIN code, personal ID numbers, and even keystroke patterns.

Your Devices
Always related to something you have with you at the moment of the login. This translates into one-time SMS messages with codes, hardware tokens, dedicated SIM cards or USB sticks, ID cards, and even key fobs.

Your Biometrics
These are things no one could ever hack in an easy manner. Things like face or voice recognition, retina or fingerprint scans, handwriting, and even DNA won’t be easily hacked during an authentication process. These are really expensive to implement though, so you probably won’t be dealing with this kind of authentication too often.

Why Should You Use It?


If just being safer from predatory hackers when browsing isn’t enough to make you jump and enable two-factor authentication in your accounts, here are some reasons to consider it.

Passwords Aren’t Safe
90% of all employee passwords could be cracked in less than six hours by using a simple brute-force attack with a decent computer. People think they’re passwords are safe; they’re not.

Hackers Evolving
Password theft gets more refined every day; methods like phishing, keylogging, and pharming are used to find weaknesses and exploit them. To highlight this fact, know that the number of successful breaches went up by almost 30% from 2013 to 2014.

Too Much Exposure
Although secret questions serve as a two-factor authentication factor, it’s better to use better protocols. Due to our increasingly exposed live thanks to social media, secret questions are becoming easier to deduce and crack. Don’t wait for it to happen to you.

Although it’s easy to say that you’re safe and that your password is really well though-out, in reality, in order to enjoy the highest level of security while browsing two-factor authentication is a necessity in this day and age.
