A YubiKey have two slots (Short Touch and Long Touch), which may both be configured for different functionality. Another application using CR is the Windows logon tool The Yubico Authenticator does not use CR in any way. initialization: add a secret to the Yubikey (HMAC-SHA1 Challenge-Response) factor one is the challenge you need to enter manually during boot (it gets sha256sumed before sending it to the Yubikey) the second factor is the response calculated by the Yubikey ; challenge and response are concatenated and added as a password to a luks key slot. so mode=challenge-response Once your YubiKey (or OnlyKey, you got the point…) is set up, open your database in KeePassXC, go to File / Change master key, enable Challenge Response and then save the database. The current steps required to login to a Yubikey Challenge-Response protected Keepass file with Strongbox are: generate a key file from the KDBX4 database master seed and HMAC-SHA1 Challenge-Response (see script above - this needs to be done each time the database changes) transfer the key to iOS,I used KeePassXC to set-up the challenge response function with my YubiKey along with a strong Master Key. The first command (ykman) can be skipped if you already have a challenge-response credential stored in slot 2 on your YubiKey. Ensure that the challenge is set to fixed 64 byte (the Yubikey does some odd formatting games when a variable length is used, so that's unsupported at the moment). Program an HMAC-SHA1 OATH-HOTP credential. The YubiKey will wait for the user to press the key (within 15 seconds) before answering the challenge. YubiKey challenge-response USB and NFC driver. Using the yubikey touch input for my keepass database works just fine. 3 Configuring the System to require the YubiKey for TTY terminal. When unlocking the database ensure you click on the drop down box under "Select master key type" and choose "Password + challenge-response for KeePassXC". ykpersonalize -v-2-ochal-resp-ochal-hmac-ohmac-lt64-ochal-btn-trig-oserial-api-visible #add -ochal-btn-trig to require button press. The YubiKey secures the software supply chain and 3rd party access with phishing-resistant MFA. In this example we’ll use the YubiKey Personalization Tool on Mac, but the steps will be very similar on other platforms.
