Easy and strong authentication with the security key YubiKey.

Secure and safe authentication for shared PCs: Security key - YubiKey.

YubiKey is one of the devices known as "security keys (hardware tokens)" that can be used for the highest level of security in multi-factor authentication. The basic way to use a YubiKey is simply to insert it into a USB port and touch it. It can be used on various operating systems without the need for dedicated software or drivers. The number of supported services is increasing year by year, and it is gaining attention as a next-generation security solution. Manufactured by Yubico, based in the United States and Sweden, YubiKey supports the latest protocols such as FIDO2 as well as traditional authentication protocols like TOTP, enabling strong two-factor authentication, multi-factor authentication, and passwordless authentication with a single tap. However, one of the factors hindering its adoption is the cost and effort involved in implementation. To reduce the burden at the time of adoption and make a more robust security solution accessible, a subscription service called YubiKey as a Service is also available.
