Deliver exceptional security with FIDO2 and U2F.

The Security Key series from Yubico - an overview

The Security Key series from Yubico combines a hardware-based authentication cryptography with the open standard protocols; U2F and FIDO2 protocols to prevent account hijackings. There are two security keys in the series - Security Key and Security Key NFC.

The Security Key series works directly with hundreds of services that already support FIDO U2F and FIDO2 authentication protocols including Microsoft accounts (for password-free login), Google, Facebook, Twitter, Dropbox, a growing list of password managers and several DO2 and U2F compatible websites.

No additional software is required and authentication is simple, fast and reliable. Just insert either Security Key or Security Key NFC into a USB port and verify with a simple swipe of your finger. You can also click Security Key NFC on an NFC-enabled device for fast, easy, and secure authentication. The Security Key series is shock and water resistant, does not require batteries, has no moving parts and is always on and available so you can log in to your accounts with just one movement.

Flexible authentication options - password-free, 2FA and MFA

FIDO2 and U2F are modern authentication protocols that provide a high level of security using key encryption. FIDO2 marks a development of U2F by now enabling several user scenarios including strong asymmetric cryptography and support for password-free login plus PIN.

With these features, the Security Key series can replace weak static usernames/passwords with a strong password-free and hardware-supported security solution that ensures that this information cannot be reused or shared between different services. This helps protect against phishing and MiTM attacks, and also reduces server-related risks. These protocols are also privacy protected, with no personal information stored on the device, which meets the security requirements even if the key were to be lost.
