YubiKey 5 Series

Multi-protocol security keys supporting FIDO2 passwordless authentication


YubiKey 5 NFC

NFC-enabled multi-protocol security key with FIDO2 passwordless authentication

5th Generation of Strong Authentication Security Keys

YubiKey 5 is a series of compact USB security keys enabling multi-factor authentication. Now comes with the FIDO2 passwordless authentication support and a USB + NFC option — YubiKey 5 NFC. Multi-factor authentication combined with hardware solutions allows improving accounts protection at all levels. It is widely known that one-time SMS passwords are vulnerable to hacks and can’t offer the appropriate level of defense. Troubles caused by hacking attacks and SIM cards cloning can be avoided by using hardware keys for secure logins to applications and online services accounts. These USB keys are ready to use with Windows, Linux and macOS operating systems, as well as with popular browsers, apps and websites. The 5th generation of YubiKeys combines multiple cryptographic algorithms support with ease of use — safe login with only a touch of the button.
