YubiKey Pros & Cons

  • Strong Security: YubiKey devices use a combination of one-time passwords and public-key cryptography to provide strong two-factor protection for online accounts.
  • Convenient: YubiKey devices are small, portable, and easy to use, making it simple to add two-factor protection to your accounts, even on the go.
  • Wide Compatibility: YubiKey devices support multiple authentication protocols and are compatible with a wide range of online services and devices, including laptops, computers, and mobile devices.
  • Cost-Effective: Compared to other two-factor authentication solutions, YubiKey devices are relatively affordable and provide a high level of security for the price.
  • Requires Physical Access: Unlike some other two-factor authentication methods, YubiKey devices require physical access to the device in order to generate a one-time code.
  • Limited Compatibility: Although YubiKey devices are compatible with many online services and devices, there may be some services or devices that do not support the YubiKey.
  • Learning Curve: For first-time users, the YubiKey can require a bit of a learning curve to set up and use, especially for those unfamiliar with two-factor authentication or public-key cryptography.

What is a YubiKey?

A YubiKey is a small hardware device made by Yubico. These battery-free devices plug into your computer and (along with your password) provide you with an extra layer of security. A hacker cannot intercept this type of verification as they would physically need your device and your username/email and password to access your accounts.

Yubikeys are also very durable, waterproof and crush resistant. Plus they come with a keyhole ring and chain so that you don’t lose them. Use a USB-A connector to your computer and a wireless NFC for your phone. NFC, which stands for “Near Field Communication“, allows phones, tablets, laptops, and other devices to easily share data with other NFC-equipped devices.

Once you register your YubiKey with supported platforms or apps, tap your YubiKey for easy, strong two-factor authentication for computers, networks, and online accounts. With no need for text messages or one-time passcodes.

What is 2 Factor Authentication (2FA)?

2-Factor Authentication (2FA) is when you are asked to enter your username and static password, then for another piece of proof that you are who you say you are.

18 million login credentials are compromised daily, and one of the most important steps to securing your online presence is enabling a form of 2-factor authentication.

One of the most common forms of 2FA is the text that you receive on your mobile phone. This usually contains a string of numbers, characters, or a combination of both. However, this can come with an element of risk, as a hacker could also potentially compromise this system too. Another way is either using a secure app on your phone like Google Authenticator or Authy. Or by using a hardware device like a YubiKey 5 NFC.
