Set Up Two-Factor Authentication and Outsmart Hackers

In today’s digital world, securing your online accounts (Facebook, email, WhatsApp, X, Instagram, Telegram, TikTok, etc.) is more important than ever. While a strong password is essential, it is not enough to protect you from hackers. This is where two-factor authentication (2FA) comes into play. 2FA adds an extra layer of security by requiring two forms of identification before granting access to your account. This means even if someone knows your password, they will not be able to log in without the second form of authentication, which requires the passkey or authentication code. This is how to set up two-factor authentication and outsmart hackers.

Step 1: Choose Your Preferred 2FA Method

Choosing your preferred 2FA methods comes with choice and knowing which is best for you. You may choose the SMS or authentication app. Some of these methods have their strengths and weaknesses depending on what you want. Methods used to are:

Authentication App

An authentication app (like Google Authenticator, Authy, or Microsoft Authenticator) generates a unique code every 30 seconds. This method is highly secure, as the codes are not transmitted over the internet and cannot be intercepted. Once you have your device with you, you are secured. Here’s how they work and why they are considered highly secure:

How It Works:

1. Installation: You first install the authentication app on your smartphone or another trusted device from the Google Store or Apple Store.
2. Linking to Account: During the setup of 2FA on a website or app, you will scan a QR code or enter a setup key into the authentication app, which links the app to your account.
3. Code Generation: The app generates a unique, one-time code every 30 seconds. These codes are randomly generated using an algorithm that is synchronised between your app and the service you’re securing.
4. Authentication: When you log into your account, you will enter your password as usual, but you will also need to provide the code generated by the authentication app. This code is valid for only a short period (typically 30 seconds), adding a time-sensitive layer to your security.

Why It is Highly Secure:

1. Offline Generation: Unlike SMS-based 2FA, the codes generated by authentication apps are created and stored on your device itself, not transmitted over the internet. This means that hackers cannot intercept the codes through network-based attacks such as SIM swapping or man-in-the-middle attacks.
2. Time-Sensitive: The codes are constantly changing every 30 seconds, which makes it difficult for attackers to use a code after the time window has expired.
3. No Reliance on Email or Phone: Since the app generates codes independently of email or phone signals, it is not vulnerable to common risks like phishing or SIM swapping, which can compromise SMS-based 2FA or email-based methods.
4. Device Ownership: As long as you have your device with you, the app remains secure. The unique codes are only accessible through the app installed on your device, adding a layer of physical security to the process.

SMS/Text Message

SMS/text message as a two-factor authentication (2FA) method involves receiving a one-time code sent to your phone number via a text message. This code is used alongside your password when logging into an account, adding an extra layer of security. Here is how it works and why it is less secure than other 2FA methods like authentication apps.

How It Works:

1. Setup: When you enable 2FA on an account, you will link it to your phone number.
2. Code Sent: When you attempt to log in, the service will send a unique, one-time code to your phone via SMS.
3. Verification: You enter the code you receive on your phone into the login screen to gain access to your account.

Why It is Less Secure:

1. Vulnerability to Interception: SMS messages can be intercepted by hackers using various techniques, such as SIM swapping or man-in-the-middle attacks. In a SIM swap attack, a hacker tricks your mobile carrier into transferring your phone number to their own SIM card. This allows them to receive all your text messages, including 2FA codes, which can give them access to your accounts.
2. Phone Number Targeting: Since SMS-based 2FA relies on your phone number, it becomes a target for attacks. If a hacker has access to your phone number, they could potentially bypass the 2FA process.
3. Phishing: Hackers can also use phishing techniques to trick you into revealing your SMS verification code. For instance, they may send fake login alerts or messages asking you to enter the code on a fraudulent website.

E-mail

Email verification is a commonly used security feature where, when logging into an account, a website or service sends a one-time verification code or link to your registered email address. You would then need to access your email, retrieve the code or link, and input it into the login page to complete the authentication process.

While this method does offer some level of security beyond just using a password, it is not as robust as other two-factor authentication (2FA) options. Here is why:

Pros:

Email verification adds an extra layer of security compared to relying only on a password.

Cons:

Vulnerability of Email Accounts: Email accounts are prime targets for hackers. If your email is compromised, attackers can bypass email-based 2FA and access your other accounts.

Email Account Compromise: If hackers gain access to your email, they can intercept verification codes, rendering the security measure ineffective.

Phishing risks: Hackers may send fake emails that trick you into entering login credentials on fraudulent websites, bypassing the verification process.

Delays in Email Delivery: Verification emails may be delayed or caught in spam filters, preventing timely access to your account.

Lack of Uniqueness: Unlike authentication apps or SMS codes, email verification uses the same code for a longer period, which can be intercepted and reused by attackers.

Step 2: Access the Security Settings of Your Account

Now that you have chosen your preferred method, it is time to enable 2FA on your accounts. For most services, you will find 2FA settings under the Security or Account section. Below are some specific instructions for popular platforms:

• Google: Visit the Security section of your Google Account, then select 2-Step Verification.
• Facebook: Go to Settings >> Security and Login >> Use two-factor authentication.
• Twitter: Head to Settings and privacy >> Privacy and safety >> Security >> Two-factor authentication.

Look for a section called Two-factor authentication or login security to start the setup process.

Step 3: Enable Two-Factor Authentication

After accessing the 2FA settings, you will be prompted to enable the feature. Follow the on-screen instructions, which will usually involve:

• Entering your password to confirm your identity.
• Choosing your preferred 2FA method (authentication app, SMS, etc.).
• Verifying your phone number (if using SMS) or scanning a QR code (if using an authentication app).

For example, if you choose an authenticator app, you will scan a QR code with your app, which will generate a code for you to enter on the website to confirm the setup.

Step 4: Set Up Your Chosen Verification Method

Depending on your choice of 2FA method, the setup will vary slightly.

Using an Authenticator App

1. Download an authenticator app (Google Authenticator, Authy, or another trusted app).
2. Open the app and scan the QR code displayed on the website or enter the key manually.
3. The app will generate a 6-digit code. Enter this code on the website to complete the setup.

Using SMS/Text Message

1. Enter your phone number.
2. You will receive a text message with a 6-digit code.
3. Enter the code on the website to confirm your phone number is linked to your account.

Using Biometrics

1. If your device supports it, you can set up fingerprint or facial recognition in your account settings.
2. Enable biometrics by following the on-screen instructions.

Step 5: Test and Confirm Your Setup

Once 2FA is enabled, log out of your account and try logging back in to make sure everything works. You should be prompted to enter the verification code from your chosen method (either via the authenticator app, SMS, or biometrics). This is your chance to ensure that everything is set up correctly.

Step 6: Backup and Recovery Options

It is important to have a backup plan in case you lose access to your 2FA device. Many platforms offer backup codes that you can store securely (like in a password manager) or print out. If you lose access to your authentication app or phone, these codes will allow you to regain access to your account.

Some services also allow you to set up a backup phone number or email address to receive authentication codes.

Common Issues and Troubleshooting Tips

Sometimes, things don’t go as planned during the 2FA setup. Here are a few common issues and how to troubleshoot them:

• Not receiving SMS codes: Ensure that your phone number is correct and that you have a strong signal. If you are still not receiving codes, try using an authenticator app instead.
• App Code Not Working: Double-check that you are entering the code promptly. Authenticator codes change every 30 seconds, so make sure you are entering the code before it expires.
• Unable to Log In: If you are having trouble logging in due to 2FA, use any backup codes you have saved or follow the platform’s recovery process to regain access.
