YubiKey: Hardware Authentication Device
A small USB device generating one-time passwords for secure login, protecting access to computers, networks, and online services with strong two-factor authentication.
What is YubiKey?
YubiKey is a hardware authentication security key manufactured by Yubico. It is a small USB device designed to protect access to computers, networks, and online services by providing strong two-factor and multi-factor authentication.
The YubiKey works by generating one-time passwords known as one-time passcodes (OTPs). When the YubiKey button is pressed, it emits a 44-character one-time password that consists of an ID unique to that YubiKey and an encryption key. This password changes with every button press and allows the user to securely log in without typing static usernames and passwords that could be phished.
In addition to one-time passwords, YubiKeys support other authentication protocols like FIDO U2F, FIDO2, and smart card capabilities. This allows the YubiKey to integrate with hundreds of online services and provide strong hardware-backed authentication. Modern YubiKeys can store and encrypt authentication keys for multiple online accounts and services.
YubiKeys are secure, easy to use, and do not require any client software or connectivity, making them a popular second factor authentication choice for both individuals and organizations looking to improve login security and prevent account takeovers.
