A YubiKey is a small USB device that provides an additional layer of security when accessing online accounts or devices. It generates a unique, one-time password (OTP) that is required in addition to your regular password. This means that even if your password is compromised, an attacker would still need physical access to your YubiKey to gain access to your accounts.
It helps to protect against phishing attacks
One of the main benefits of using a YubiKey USB is that it helps to protect against phishing attacks. Phishing attacks are a common way for attackers to gain access to your accounts by tricking you into entering your login credentials on a fake website. With a YubiKey, the attacker would need your password and the physical YubiKey to gain access to your accounts.
Useful for protecting against keyloggers
YubiKeys are also useful for protecting against keyloggers, which are programs that record your keystrokes and could potentially capture your login credentials. Because a YubiKey generates a one-time password that is not entered using a keyboard, keyloggers would be unable to capture it.
Types of Yubikeys
Several types of YubiKeys are available, each designed for specific use cases. The YubiKey 5 series, for example, is a multi-protocol key that can be used for a wide range of applications, including password management, secure login, and secure communication. The YubiKey NEO is a smart card-enabled key that can be used for secure login, digital signatures, and two-factor authentication.
To use a YubiKey, you must set it up with the online accounts or devices you want to protect. This typically involves installing the YubiKey software and following the prompts to register your key. Once your YubiKey is set up, you can log in to your accounts or access your devices by inserting it into a USB port and pressing the button on the key.
Convenient to use
In addition to providing an extra layer of security, YubiKeys are also convenient to use. Because they are small and portable, you can easily carry them and use them on any device with a USB port. They are also durable and resistant to water, dust, and other environmental factors, making them ideal for various settings.
