What Is Two-Factor Authentication and Why Is It Important?

Two-factor authentication, often referred to as 2FA, adds an extra layer of security to user logins. It requires additional steps to confirm a user’s identity.

Imagine it like entering a bar: first, one bouncer lets you in, and then another bouncer inside asks for more information before granting access. Similarly, 2FA ensures that even if someone gets hold of your login details, they can’t access your account without an extra verification step.

When 2FA is enabled on a platform, it usually asks for a verification code sent to your registered mobile number. Alternatively, it might involve using a fingerprint scan or a security app on your phone.

This ensures that only the genuine account owner can log in. Even if hackers know the login details, they can’t access the account without the verification code or the owner’s unique biometrics.

In today’s era, technology has surged ahead, and while fraudsters and cybercriminals have advanced their methods of breaching user accounts, security measures have also evolved.

Users can easily activate these security features as recommended by various applications. This ensures robust protection and lasting peace of mind, shielding users from hacks even if login details are exposed.

However, it’s important not to be complacent. Creating strong, unique passwords for each account is also important, and remember to keep track of them securely. Just don’t write it in a notebook and leave it somewhere.

Two-Factor Authentication for Dummies

2FA is essential for all accounts, whether they contain valuable assets or not. It safeguards your identity and prevents unauthorized access.

An account represents you, and preventing strangers from taking it over is vital. The true owner should be the only one with access, which requires proving ownership during login.

However, it’s important to clarify that 2FA is more than just a fingerprint, face scan, or verification code sent to your phone. OTP is a single-layer security, which is only a part of the two-factor authentication system.

Before you secure your accounts, here’s what you must understand about the layers of two-factor authentication. If you haven’t already, it’s time to read and take action.

Personal questions (ex: name of your pet)

Remember those security questions you answered when creating your account? Questions like your favorite pet or your first car?

They’re more important than you might think. If you can’t recall the answers you provided, regaining access to your account on another device or resetting a forgotten password can be a challenge.

These personal questions come into play when a suspicious login is detected. They help verify your ownership by asking for details only the true account owner – who originally set up and answered those questions – would know.

If you haven’t already answered these verification questions, it’s a good idea to provide the details seriously. These answers could be crucial for account-related emergencies.

You don’t need to memorize them; questions like your first pet’s name tend to stick in your memory. Only the genuine account owner would know the accurate details for these questions.

If a scammer attempts to access your account and encounters these questions, they’d need to know your first car or they’d be denied access.

Smartphone & Authentication Tokens

Have you experienced logging into your Google Account on a new device and being prompted to open YouTube on the original device?

This is a form of authentication used by companies like Google. It’s because your Google account serves various purposes, including Gmail, business, classroom, and personal uses. This step enhances security by requiring verification through a device already logged into your account.

Additionally, you receive notifications within the app about login attempts, along with device and location details. This extra layer of security prevents unauthorized access. Scammers would be less successful if you have this authentication set up on your account.

Verification through a trusted device isn’t the sole method for this type of authentication. Another common approach is using a special authenticator token, saved exclusively on your main device.

When you attempt to log in from another device, this token is needed to grant access. Think of your primary phone as a key to a lock – it’s crucial not to lose that key.

In both cases, security is tight and only the person possessing the correct key and mobile device can successfully log into the accounts.

Secondary factor authentication (SMS code & user biometrics)

This layer of two-factor authentication is widely used and typically follows password verification. It involves providing extra information to confirm your identity during login.

One common method is using a one-time code (OTP) sent to your phone, which you’ll enter on the website. If you’ve enabled 2FA, this 4 or 6-digit code must match the one sent to your device.

Even the cleverest scammers can’t predict these OTP digits, making it a strong security measure. In more advanced cases, biometrics are employed.

This means using your registered fingerprint or facial recognition, a more sophisticated technique that only the legitimate account user possesses. The system checks that the provided biometric data matches before granting access.

In today’s internet, relying solely on a password is insufficient. Unlike a few years back, scammers now face greater difficulty accessing user accounts.

While a few might succeed by forcefully entering a user’s device and installing tracking malware for intercepting verifications, most of these malware are detectable by antivirus software. If you haven’t already, it’s strongly recommended to install antivirus software to safeguard against such threats.

More uses for Two-Factor Authentication

Two-factor authentication serves a broader purpose beyond just initial logins on new devices. Many applications and platforms employ this security measure not only for login protection but also for situations where confirming the account owner’s actions is crucial.

The versatility of two-factor authentication is evident in various scenarios. Here are some common use cases highlighting why it’s essential to activate it for your own safety:

Online transactions and payments

During online purchases, you often encounter the need for an OTP sent to your mobile phone. However, some people skip this step or choose to “Trust this device” to simplify their online shopping process.

This practice can be risky, especially considering the financial stakes involved. Money matters and so the demand for security should be heightened as well.

If your financial account lacks 2FA, hackers could swiftly drain your funds and misuse your account for purchases that benefit them, not you. Preventing this requires safeguarding your account with two-factor authentication.

OTP isn’t the sole method for verifying online transactions. For Apple devices, a facial biometric scan is used to ensure the person making the purchase is indeed the account owner.

This security feature matches the scanned face with the registered one on the Apple ID system. Nearly all Apple devices have this, contributing to their strong security reputation.

Does this slow down the purchase process? Not at all. With just a double click and a quick face scan, the transaction is seamlessly and securely completed.

This efficiency highlights the benefits of this approach. While it might not always be facial recognition, other authentication methods exist. It’s crucial to select a method that can’t be exploited by cybercriminals.

Logging into important accounts

When logging in to new devices, you will always encounter 2FA. Once verified, you gain ongoing access to that device. However, certain critical platforms differ in this aspect.

I am referring to online banking, domain hosting, files on the cloud, and potentially cryptocurrency accounts. These tight security measures are necessary due to the substantial sums involved in these accounts.

For instance, bank accounts hold significant funds vulnerable to loss via cybercrime. Hosting and domain accounts store valuable assets like high-priced domains and websites.

Cryptocurrency accounts also fall into this category; the unregulated nature of crypto makes retrieval impossible once lost.

In addition to that, cloud hosting stores your files on secure servers so you do not have to worry about disk space. However, it can be openly accessible for someone with the right login credentials. Adding a security layer is essential to protect important files. It contains important files, and cybercriminals might exploit it against you.

While 2FA can seem repetitive, especially for these accounts, the annoyance is minor compared to the potential loss of substantial assets on these platforms.

Imagine opening a vault – you close it after use, right? Similarly, certain accounts require the same kind of constant protection.

Two-factor authentication needs to be tightly secured at all times, irrespective of device trust. Although this might feel a bit tedious, these platforms aren’t accessed as frequently as social media.

We highly suggest activating strong authentication, especially for accounts holding valuable assets. Just as you ensure a vault’s security, these measures safeguard what matters most, as long as you know the code, you can enter.

Workplace Accounts

While not every workplace adopts this security measure, it’s commonly used to ensure unauthorized access is prevented. This is especially important for remote workers needing system access to submit documents and perform tasks.

Scammers often target employees to exploit workplace details for ransomware attacks or extortion. To counter this, companies implement an extra layer of security.

Employees must complete a two-factor authentication before accessing the company system, whether they’re at work or remotely.

Prominent tech companies and tech-savvy entities understand the necessity of this measure, especially when safeguarding the entire company.

A single vulnerability can trigger a chain reaction, as some companies have painfully learned through targeted scams. Impostors, pretending to be genuine employees, exploit their accounts for unauthorized system access.

They often target individuals with elevated system access, seeking to obtain critical insider information.

Bottom Line

Now that you understand the power of two-factor authentication, particularly when it comes to dealing with scams and fending off malware attacks, you can see its role as a vital defense. With a strong barrier in place, your valuable assets are shielded from being wiped out.

So, how can you activate two-factor authentication? The process can usually be found in the Settings section of the platform or website you’re using.

We also recommend answering all required security questions with clarity and ensuring your biometrics are scanned with a clean appearance and clean hands (for fingerprint recognition). Small oversights could lead to being locked out of your account.

Above all, prioritize your online safety while browsing the internet. This precautionary approach can make a substantial difference, in fact, a big one.
