Want to protect your account from hackers? Use two-factor authentication
These days, hacking attempts are fairly common on the internet. Attackers can breach social networks or even create fake websites to trick you into giving away your confidential usernames and passwords. This can lead to major cases of financial or identity frauds, but you can avoid that (mostly) by shielding your account with an additional step - two-factor authentication. Let's know more about it.
What is two-factor authentication?
As the name suggests, two-factor authentication is a way of securing accounts by creating an additional layer of security. 2FA works in different ways, but it is all about verifying your identity by combining something you know (username, password) with something you have, be it a code sent on your phone/email or fingerprint. It is similar to using ATM and PIN for withdrawing money.
This way, hackers won't be able to get in
This means even if hackers manage to steal your passwords or trick you into giving them away, they won't be able to log into your account unless they'll complete the two-factor authentication process in accordance with the method chosen by you.
But, is two-factor authentication really necessary?
You may think that hacking attempts at individual accounts are not that common, but people can see you type your password or steal it using malware or phishing techniques. Then, if your account is not secured, they could steal money or even commit cybercrimes by posing as you. The matter could get worse if you're using the same password for other websites as well.
Common ways to enable two-factor authentication
Two-factor authentication can be used with the help of a code sent - either via SMS or through a specialized app. Most sites offer SMS-based authentication because it's easy to use, but do note that it is the least secure option. Texts are not end-to-end encrypted and can be stolen, but app-based authentication codes are sent over an HTTPS connection and are more secure.
However, a physical security key is the best option
App-based authentication is more secure than SMS-based verification, but they both can prove problematic if you lose your phone. This is where the strongest option comes in - a physical key designed to approve your login. On entering the password, you'll be prompted to insert the cryptographically unique USB stick, which can be kept safe and would be difficult for hackers to obtain.
How to start using two-factor authentication
To start using two-factor authentication, create a list of sensitive website and platforms, like your email and social profiles, you want to secure. After this, visit the most valuable platform first and turn on two-factor authentication from settings.
