-touch-eject - The button will insert and eject the smart card.

The 80 will be ignored, and it will behave like 6.

Note: Some examples use mode number 86, which is invalid. Ykman uses the term 'modes', named OTP, FIDO, and CCID. The following table shows which protocols use which interfaces: All three can be enabled or disabled independently, allowing control of their associated protocols. Two of the interfaces implement the USB HID (Human Interface Device) device class the third is a smart card interface (CCID). Challenge-Response requests (calculated using either Yubico OTP mode or HMAC-SHA1 mode)ĭepending on the YubiKey model, the device provides up to three different USB interfaces.Blinks steadily when a button press is required to permit an API response.Blinks once when plugged in, useful for troubleshooting.(Note that static passwords are vulnerable to keyloggers.) Keystrokes (emulating a USB keyboard), used to type static passwords and OTPs.The YubiKey transforms these inputs into outputs:

The LED will illuminate to prompt the user. This is the default behavior, and easy to trigger inadvertently. Trigger a static password or one-time password (OTP) (Short press for slot 1, long press for slot 2).Depending on the context, touching it does one of these things: The YubiKey takes inputs in the form of API calls over USB and button presses. YubiKey Full Disk Encryption - Use challenge-response mode to create strong LUKS passphrases.Enables web browsers to use the U2F protocol for authentication with your YubiKey.

Yubico Authenticator version 6 is a complete rewrite of the application using the Flutter framework. Yubico Authenticator 6 for Desktop - Yubico Authenticator 6 is an application for managing the YubiKey's second factor credentials.Support the newer OATH implementation (YubiKey NEO and 4) as well as the older slot-based implementation (YubiKey Standard and Edge). Yubico Authenticator for Desktop - GUI to read OATH codes from your YubiKey over USB.Yubico PAM-U2F - PAM user authentication with U2F.

Yubico PAM - PAM user authentication with either Yubico OTP or challenge-response.

|| yubikey-personalization, yubikey-personalization-gui Authentication tools More powerful than ykman, but harder to use.

YubiKey Personalization - Library and tool for configuring and querying a YubiKey over the OTP USB connection.
