If you’re reading this, you’ve probably used two-factor authentication (2FA) for an online account, like a WordPress website or a Google account. With 2FA, you must use your primary login credentials, such as email or username and password, along with another authentication method, like a one-time passcode (OTP) sent via email, SMS, or other channels like WhatsApp.
Although some find it inconvenient to enter their login credentials and then authenticate again with a code sent to their device or an app, this effort is worthwhile because 2FA protects your accounts from several security threats. If you’re still hesitant about using 2FA on your online accounts, I recommend turning it on immediately. Hey is why
Protection Against Brute Force Attacks
Brute force attacks involve hackers using automated tools to guess your password by trying countless combinations. Recent studies show that over 80% of all hacks are caused by brute force attacks or stolen credentials. Without additional security measures, these attacks can easily compromise accounts with weak or predictable passwords.
Two-factor authentication (2FA) protects against this by requiring a second factor, such as a code from an authentication app or a hardware key. With 2FA enabled, it becomes nearly impossible for hackers to gain access, even if they eventually guess your password. It provides an extra security layer that attackers must bypass to access your account, enhancing its security.
Your Accounts Will Remain Safe Even When Your Device is Stolen
If your smartphone or laptop is stolen, enabling 2FA on important online accounts like banking apps could be the difference between exposing all your online accounts and saving them. This is especially true if you use authentication apps that require biometrics to verify your identity.
While the thief may have your device, they will still need the second authentication factor—like a biometric scan, security key, or access to an authentication app—to log into your accounts. Even with the stolen device, the presence of this second factor keeps your sensitive data secure.
It Could Be a Cover-Up for Your Weak Password
A weak password that is easy to guess or reused across multiple accounts is a significant security risk. While creating strong passwords is essential, 2FA can act as a safety net if your weak password is compromised by attackers.
Even if an attacker guesses your weak password, they still cannot bypass the second layer of security provided by 2FA. This makes it a crucial backup for users who may not follow best practices for password creation. However, having a strong password (preferably generated with a password manager) should be your first line of defense.
Peace of Mind
2FA provides peace of mind by reducing the constant worry about cyberattacks and unauthorized access to your accounts. Knowing that an extra layer of security is in place can make you feel more confident about using online services, especially for sensitive tasks like banking or managing personal information. Even if a data breach occurs and your credentials are exposed, 2FA ensures that attackers cannot easily gain access.
Best Practices for using 2FA
To fully benefit from 2FA, it must be implemented effectively. Here are some best practices I recommend:
Use More Secure 2FA Methods Like Authentication Apps and Not SMS.
While SMS-based 2FA is better than no 2FA at all, it is vulnerable to several security risks, such as SIM swapping attacks and interception of messages. Authentication apps like Google Authenticator or Microsoft Authenticator offer a more secure alternative by generating time-based one-time passwords (TOTP) directly on your device.
These codes are not transmitted over the network, reducing the risk of interception. By using authentication apps, you ensure that your second factor is more reliable and less prone to being compromised, which significantly improves your account’s security. I recommend using Google Authenticator for most people because it’s easy to use and offers the basic functionality needed.
Use It on All Supported Accounts
Enabling 2FA on all accounts that support it ensures consistent protection across your digital footprint. Hackers often exploit the weakest link in your security chain, so leaving some accounts without 2FA makes you vulnerable. The good news is that most of the popular online platforms we use support offer 2FA, and some even include the more secure passkeys as an option.
From email and social media to banking and cloud services, every account that supports 2FA should have it enabled. This practice minimizes the chances of unauthorized access and prevents attackers from using one compromised account to access others.
Consider Passwordless Authentication Solutions
Passwordless authentication solutions are becoming increasingly popular for their convenience and security. These methods eliminate the need for passwords, addressing the common risks of weak or reused passwords. If any of the platforms you use offer Passwordless methods like passkeys with biometric verification, security keys, or device-based authentication, make sure to choose them.
Key Takeaway
The main takeaway from this article is that using 2FA should be a must if the platform you use supports it. Fortunately, many platforms support intuitive 2FA methods, like passkeys, which require only biometric authentication or a few taps in your authentication app to authenticate. Some platforms even have condition-based 2FA, meaning it’s only required in certain situations, such as when you’re using a new browser or device to sign in. Given this level of convenience, there’s no valid reason not to use 2FA, considering the added security it provides for your online accounts.
