I personally use a combination of an encrypted password vault to store secrets and Yubico’s YubiKey to act as my security key and Google Authenticator as my one time password (OTP) generator. It’s relatively easy for folks to get your passwords these days – especially with the frequent vendor breaches – making something like two-factor authentication (2FA) or multi-factor authentication (MFA) a necessity. Securing your access to resources should be top of mind. 4 YubiKey Security Key Configuration for Android NFC.On Windows, the smart card functionality can be enhanced with the YubiKey Smart Card Minidriver. This application provides a PIV-compatible smart card. Accessing this application requires Yubico Authenticator.

For more information, refer to the YubiKey 5 FIPS Series Technical Manual. In place of the U2F functionality, use the FIDO WebAuthn application. Note: The YubiKey 5 FIPS Series U2F application cannot be used in a FIPS 140-2 Level 2 mode. These credentials, which are protected by a PIN, enable passwordless login, where the YubiKey, unlocked by a PIN and authorized by touch, can log you in to your accounts without entering a username or password. The FIDO2 application allows for secure single and multi-factor authentication, and can store up to 25 resident credentials. All of the applications are available through both interfaces. The YubiKey 5C NFC FIPS uses a USB 2.0 interface as well as an NFC interface. Support for OpenPGP was added in firmware version 5.4.3.

Note: The YubiKey 5 FIPS Series with initial firmware release version 5.4.2 does not support OpenPGP. The YubiKey 5C NFC FIPS has five distinct applications, which are all independent of each other and can be used simultaneously.
