Saving a few bucks on a backup key can leave you with a single point of catastrophic failure. They come with a hole that lets you attach one to your keychain while the other stays in another safe, trusted location.</p>https://bitlex.li/tutorials/yubikey-management/Mon, 13 Apr 2026 00:00:00 +0000https://bitlex.li/tutorials/yubikey-management/<h2 id="yubikey-management-tools-installation">Yubikey Management Tools Installation</h2> <p>We need yubikey-manager Smart Card Daemon middlware.</p> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span>sudo pacman -S yubikey-manager pcsclite ccid </span></span><span style="display:flex;"><span>sudo systemctl enable --now pcscd.service </span></span><span style="display:flex;"><span>sudo systemctl enable --now pcscd.socket </span></span></code></pre></div><p>Verify if the key is detected:</p> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span>ykman info </span></span></code></pre></div><pre tabindex="0"><code> @slexi  ykman info Device type: YubiKey 5C NFC Serial number: 25997589 Firmware version: 5.4.3 Form factor: Keychain (USB-C) Enabled USB interfaces: OTP, FIDO, CCID NFC transport is enabled Applications USB NFC Yubico OTP Enabled Enabled FIDO U2F Enabled Enabled FIDO2 Enabled Enabled OATH Enabled Enabled PIV Enabled Enabled OpenPGP Enabled Enabled YubiHSM Auth Enabled Enabled </code></pre>
