Why use hardware security keys in computer

With the increasing number of cyber attacks, securing your online accounts has become more important than ever. Hardware security keys is a small device that can provide an extra layer of security for your online accounts, making it much harder for hackers to access them. In this blog, we will discuss why you should consider using a hardware security key for your computer.

How hardware security keys work

Hardware security keys are physical devices that are used to secure online accounts by providing an extra layer of authentication. They work by using cryptographic algorithms to create a secure connection between the user’s device and the online service that they are trying to access. This secure connection is used to verify the identity of the user, and to prevent unauthorized access to the user’s accounts.

The most common type of hardware security keys is the Universal Second Factor (U2F) key, which uses public-key cryptography to create a secure connection. When a user wants to log into an online service that supports U2F, they plug the hardware security key into a USB port on their device and touch the button on the key. This sends a cryptographic challenge from the online service to the key, which the key then signs with its private key. The signed challenge is then sent back to the online service, which uses the user’s public key to verify the signature and grant access.

By using a hardware security key, users can greatly reduce the risk of their online accounts being compromised by attackers. This is because even if an attacker is able to obtain the user’s password, they will still be unable to log into the user’s accounts without access to the hardware security key. Additionally, hardware security keys are designed to be resistant to tampering and hacking, making them a secure and reliable way to protect online accounts.

Two-Factor Authentication

Hardware security keys provide two-factor authentication (2FA), which means that in addition to your password, you also need to have the key in order to access your account. This makes it much harder for hackers to access your accounts, as they would need to have both your password and the hardware security key.

Easy to Use

Hardware security keys are very easy to use. All you have to do is plug the key into your computer’s USB port and tap it when prompted. This makes it much easier to use 2FA than traditional 2FA methods, such as using a code sent to your phone or email.

More Secure Than Traditional 2FA

Traditional 2FA methods, such as codes sent to your phone or email, can be intercepted by hackers. Hardware security keys, on the other hand, are much more secure. The key generates a unique code every time it is used, making it much harder for hackers to intercept the code.


Hardware security keys are small and portable, making it easy to take them with you wherever you go. This means that you can use the key on any device that supports USB, making it much easier to access your accounts from anywhere.

Supports Multiple Accounts

Many hardware security keys support multiple accounts, making it easy to use the same key for multiple accounts. This makes it much easier to manage your security, as you only need to keep track of one key instead of multiple codes or devices.

In conclusion, hardware security keys provide an extra layer of security for your online accounts. They are easy to use, more secure than traditional 2FA methods, portable, and support multiple accounts. If you want to keep your online accounts secure, consider using a hardware security key.
