Two-Factor Authentication: Why the FBI Warns Against Text-Based 2FA
Two-factor authentication (2FA) has become a critical tool for securing online accounts. However, the FBI recently warned users about the risks of using text-based two-factor authentication. This outdated method leaves your accounts vulnerable to hackers, who can intercept your SMS codes through phishing attacks or telecom breaches. As a result, it’s now more important than ever to switch to safer alternatives for protecting your sensitive information.
Why Text-Based Two-Factor Authentication is Risky
The FBI and the Cybersecurity and Infrastructure Security Agency (CISA) have raised concerns about the security of SMS-based two-factor authentication. Specifically, hackers have been targeting telecom providers to intercept text messages containing verification codes. This type of attack leaves your accounts exposed, especially for sensitive data like banking, email, and social media.
Here are the main reasons why SMS-based 2FA is no longer secure:
- Hackers can intercept text messages: Text messages are not encrypted, making them an easy target for cybercriminals.
- Phishing scams are increasing: Attackers often send fake messages to trick users into clicking malicious links or sharing sensitive details.
- Telecom breaches: Hackers are exploiting vulnerabilities in telecom networks to access SMS-based codes.

Safer Alternatives to SMS-Based Two-Factor Authentication
Fortunately, there are more secure options available to replace text-based two-factor authentication. Here are the best alternatives:
1. Use Authenticator Apps
Authenticator apps, such as Microsoft Authenticator, generate secure one-time passwords (TOTP) on your device. These codes are not transmitted over the internet, making them far more secure than SMS-based verification.

2. Password Manager Apps
Password managers like Bitwarden Manager let you store and generate strong, unique passwords for every account. This reduces the risk of hackers accessing multiple accounts if one is compromised. The Best Password Managers.
3. Use Unique Passwords
Using a different password for each account is essential for reducing your risk. Even if one account is hacked, unique passwords prevent attackers from accessing others.

How to Avoid Phishing Scams
To protect yourself from phishing scams, follow these tips:
- Avoid clicking on links in unexpected or suspicious messages.
- Verify the sender of any message before taking action.
- Report and delete spam or phishing messages immediately.
By staying cautious, you can minimize your exposure to phishing attacks and keep your accounts secure.
What the Experts Say
Cybersecurity expert Yashin Manraj advises against relying on SMS-based two-factor authentication. According to Manraj, phishing attacks account for the majority of successful hacks. He recommends switching to more secure options, such as authenticator apps, to enhance account security.
Additionally, Manraj stresses the importance of using unique passwords for all accounts. He states, “Differentiating your passcodes reduces the risk of hacking by 80 to 90%.”
Moving Beyond SMS-Based Two-Factor Authentication
Ultimately, text-based two-factor authentication is no longer a reliable way to secure your online accounts. By adopting safer methods, such as authenticator apps, password managers, and unique passwords, you can significantly reduce the risk of cyberattacks. While no system is entirely foolproof, these steps will help protect your sensitive information and ensure your online safety.
