In our digital world, Two-Factor Authentication can play a crucial role in safeguarding confidential data. By combining encryption with  password protection, many businesses are enhancing their overall data security.

To make the process easier, many businesses are turning to devices like the YubiKey to ensure secure authentication without much inconvenience. But what exactly is a YubiKey and how do you use one? Let’s take a look.

What Is a YubiKey?

YubiKey is a hardware-based authenticator designed to enable Multi-Factor Authentication in PCs, VPNs, and online services. It features various verification options like one-time passwords (OTP), Universal 2nd Factor, FIDO2, and more. Unlike 2FA applications, a user cannot access the data without inserting a physical key and using the correct password.

Even if an unauthorized user gets the key, they cannot access files without the correct password. With FIDO algorithms, YubiKey is one of the securest devices for Two-Factor Authentication. Even some of the largest tech companies like  Google and Facebook use it to safeguard user accounts from hackers.
