At Comfac-IT, we are committed to ensuring your digital security. One of the most critical steps you can take to protect your online accounts is by moving away from SMS-based two-factor authentication (2FA). While SMS passwords might seem convenient, they are increasingly vulnerable to attacks, putting your sensitive data at risk.

Why is SMS-Based 2FA is No Longer Safe?

SMS-based 2FA uses your phone number to send one-time passcodes via text message. However, this method has several key vulnerabilities:

  • SIM Swapping: Attackers can trick your mobile carrier into transferring your phone number to a SIM card they control. With your phone number, they can receive your SMS codes and gain unauthorized access to your accounts.
  • SMS Interception: SMS messages are sent over unencrypted networks, making them vulnerable to interception. Tools like IMSI catchers or Stingrays can mimic cell towers and intercept your texts, including your 2FA codes.

These risks have made SMS-based 2FA an increasingly dangerous method of protecting your accounts, as attackers continue to develop new techniques to exploit these weaknesses.

Switch to Time-Based Passwords for Enhanced Security

To better secure your accounts, we recommend switching to time-based authenticator apps. These apps generate one-time passcodes (TOTP) on your device that change every 30 seconds and are not transmitted over the network, making them significantly harder for attackers to intercept.

Here are some recommended alternatives:

  • Google Authenticator: Available on Android and iOS, generating TOTP codes every 30 seconds.
  • Microsoft Authenticator: Works across Android, iOS, and Windows, providing TOTP codes, password management, and secure cloud backup.
  • Authy: Offers multi-device sync and secure cloud backup, available on multiple platforms including Android, iOS, and desktop.
  • Apple’s Built-in Authenticator: Integrated directly into iOS (from iOS 15), offering TOTP codes within the iPhone’s Settings app.
  • 1Password: A comprehensive password manager that supports TOTP generation, simplifying both password and 2FA code management.
  • LastPass Authenticator: Provides TOTP codes and one-tap push notifications, available for Android and iOS users.
  • FreeOTP: An open-source alternative for generating TOTP codes, for users who prefer open-source software.

Why You Should Make the Change

Moving to a time-based authenticator app greatly reduces the risk of unauthorized access to your accounts. Time-based passcodes are only available on your device, and they change frequently, making it nearly impossible for hackers to steal them.
