What is Yubikey? How Yubikey Works on Your Computer

What is Yubikey? This term is known as the leading safe and effective security support technology today. This technology is mainly used to protect private accounts in computers or other service accounts. If you are curious about this security technology, you can learn more in the following article.

Learn a little about 2-factor authentication

Before we get into what Yubikey is, let’s take a quick look at 2-factor authentication:

What is 2-factor authentication?

Passwords have always been a difficult problem for everyone, whether they are too simple or too complex passwords, these passwords are likely to be leaked and exposed to the outside. To solve this problem, the 2-factor authentication method – 2FA was developed to add a layer of security outside of passwords and allow users to effectively control.

2FA will require you to need two factors to log in: your own password and a tool to prove you are the owner of that account. Most messaging applications such as Zalo, Facebook, and Google services currently support 2-factor authentication.

2-factor verification methods

Before learning what Yubikey is, you need to know the popular methods to receive 2-factor verification codes today including SMS codes and emails. When logging in, the system will usually ask to enter this code as the final step. This is the simplest way without needing to authenticate using software or auxiliary applications. However, this method has lower security because emails and messages can still be attacked.

Another method is to use third-party verification applications such as Microsoft Authenticator or Google Authenticator. This allows you to receive authentication codes at any time, even without an Internet connection, and significantly increases security compared to email or SMS. However, having to open the app and enter the code manually can be inconvenient.

YubiKey is a third-party solution for 2FA technology. It is a hardware device that supports identity and password verification very quickly. To use YubiKey, users just need to plug the device into the computer and press a button. Then YubiKey will generate a unique code to verify the user’s identity. This process is fast and simple.

What is Yubikey?

YubiKey is a simple 2FA device for authentication. Widely used by many online services, applications, and computer systems, YubiKey requires users to simply press a button to complete the login process, instead of using SMS codes or authentication apps. Each YubiKey integrates a proprietary code that is used to generate authentication codes to verify the user’s identity.

Although YubiKey is not the only hardware 2FA device on the market, it is the most widely used. There are many other similar devices on the market today that provide higher security for user accounts.

What are the outstanding strengths of the Yubikey 2FA device?

Now that we’ve learned about YubiKey, let’s take a look at why YubiKey and similar 2FA devices are superior to other 2FA methods. Here are a few aspects:

  • Convenience: Email, SMS, and other authentication methods require users to manually enter/copy the code. With the YubiKey device, you just press the device button and plug it into your computer to enter the code.
  • Longer code: Other 2FA authentication methods only send a 6-digit code for you to verify your identity. The YubiKey device will not force you to enter the code manually, so you can use a longer code, thereby increasing security.
  • Easy to move: Instead of having to retype the code when changing devices, with YubiKey, you just need to unplug the device from the old device and plug it into the new device. You can then conveniently log in to other applications, even log in to multiple computer devices.
  • Hard to Hack: Hackers can break into your email or SMS, but not with a YubiKey. This hardware device generates hard-to-forge codes, making hacking difficult or nearly impossible.

These points show that YubiKey not only simplifies the authentication process but also significantly enhances security compared to other traditional 2FA methods.
