Have you ever observed the process when you log in to your accounts on a particular app or website? Most of the time, an app or website will ask you to set up two-factor authentication.
But what exactly is two-factor authentication? How does it work? Why is it important?
Continue to read till the very end and you'll have answers to all of these questions. Let's dive in!
🚀 A Quick Intro to this Topic:
These days, it's no secret that passwords alone are not enough to secure our online accounts. Cybercriminals are always looking for ways to steal personal information, including passwords, and use it for malicious purposes.
This is where two-factor authentication (2FA) comes in as an additional security measure that adds an extra layer of protection.
🦠 What is Two-Factor Authentication?
First things first, I'll be referring to two-factor authentication as 2FA cause its easier to write and it'll save time for me :)
2FA is a security process that requires users to provide two different authentication factors to verify their identity before accessing their accounts. These factors can be any combination of the following:
Something the user knows, such as a password or a PIN.
Something the user has, such as a mobile device or a hardware token.
Something the user is, such as biometric information like fingerprints or facial recognition
It essentially provides an extra layer of protection against hackers and other cybercriminals who might try to gain unauthorized access to your online accounts.
Even if they manage to obtain your password, they will still need to provide the second factor of authentication to access your account.
🤔 How to set up Two-Factor Authentication?
Enable 2FA in the account settings of the platform or website you want to secure.
Choose the type of 2FA you want to use. This can be done through a mobile app, text message, or email.
Follow the prompts to set up 2FA, which may include providing a phone number or scanning a QR code.
It's important to note that different platforms and websites may have different methods for setting up 2FA. Always check the specific instructions for the platform or website you want to secure.
Once enabled, the user will be required to provide their password or PIN, as well as a second factor of authentication, before gaining access to their account.
The second factor of authentication can be a one-time code sent to their mobile device, a push notification, or a biometric scan.
The two factors of authentication work together to provide a higher level of security than just a password or PIN alone.
Even if a cybercriminal manages to steal a user's password, they will not be able to access the account without the second factor of authentication.
👽 Why is Two-Factor Authentication Important?
You know, before starting this club I really wanted to know if it's required and does it create an impact. So I used to venture this idea to a couple of my friends.
And every time I used to embark them this idea, I used to start with a simple question, are you all mindful of a setting or an option called '2FA'? I'd then have to provide them with its full form, ie. Two Factor Authentication.
And after that, hardly 25% of them knew about this sorta concept.
So that always made me wonder if these people who are reasonably good in using their mobile devices aren't really aware of it, then what about the passive consumers of online content who have their passwords literally breached?

2FA is important for several reasons. First and foremost, it provides an extra layer of security that can help prevent unauthorized access to accounts. This is particularly important for accounts that contain sensitive information, such as financial accounts or personal data.
Additionally, 2FA can help protect against phishing attacks, where cybercriminals attempt to trick users into providing their login credentials. If a user falls for a phishing scam and gives their password, the cybercriminal still won't be able to access the account without the second factor of authentication.
Finally, many regulatory bodies now require the use of 2FA for certain types of accounts, such as healthcare or financial accounts. Compliance with these regulations is crucial to avoiding penalties or legal repercussions.
✌️ Summary:
2FA is a powerful tool in the fight against cybercrime. By requiring users to provide two different authentication factors, 2FA provides an extra layer of security that can help prevent unauthorized access to accounts and protect against phishing attacks.
It's important for users to enable 2FA whenever possible, particularly for accounts that contain sensitive information or that are subject to regulatory requirements. By taking this extra step to secure our accounts, we can help keep our personal information safe in an increasingly digital world.
