Two-Factor Authentication for Connected Cars: Why It’s Important and How to Set it Up

Connected cars are vulnerable to cybersecurity threats, such as hacking and data breaches, which can compromise the safety and security of drivers and passengers. Two-factor authentication is an effective security measure that can protect connected cars from unauthorized access. In this article, we’ll explore why two-factor authentication is important for connected cars and how to set it up.

Why is Two-Factor Authentication Important for Connected Cars?

Two-factor authentication provides an additional layer of security beyond just a password. In a connected car, two-factor authentication can prevent unauthorized access and protect against cyber threats, such as hacking and data breaches.

By requiring a second form of authentication, such as a unique code sent to a trusted device or a fingerprint scan, two-factor authentication can help ensure that only authorized individuals are accessing the car’s system. This can help prevent cyber-attacks and data breaches, protecting sensitive data and ensuring the safety of drivers and passengers.

How to Set Up Two-Factor Authentication for Connected Cars

  1. Check if Your Car Supports Two-Factor Authentication

Not all connected cars support two-factor authentication. Check with your car manufacturer to see if this feature is available for your vehicle.

  1. Set Up a Trusted Device

To use two-factor authentication, you’ll need a trusted device, such as a smartphone or tablet. Set up your trusted device by downloading and installing the manufacturer’s app.

  1. Enable Two-Factor Authentication

Once you’ve set up your trusted device, enable two-factor authentication in your car’s settings. This may involve scanning a QR code or entering a unique code to link your trusted device to your car.

  1. Verify Your Identity

When accessing your car’s system, you’ll be prompted to enter a unique code that is sent to your trusted device or to perform a fingerprint or face scan.

  1. Monitor Your Trusted Devices

Make sure to monitor your trusted devices and remove any that you no longer use or recognize to ensure the security of your connected car.


Two-factor authentication is an effective security measure that can help protect connected cars from cyber threats and unauthorized access. By following these steps and enabling two-factor authentication for your connected car, you can ensure the safety and security of yourself and your passengers. Remember, cybersecurity is an ongoing process that requires continuous monitoring and improvement to ensure success.
