<p><strong>Keyless Login</strong> brings modern, phishing-resistant authentication to your WordPress site.</p>
<p>Log in with your fingerprint, face, or a hardware security key — no password ever required or transmitted. Implemented entirely in pure PHP using only the built-in <code>openssl</code> extension. No Composer, no vendor folder, no third-party libraries.</p>
<h4>How It Works</h4>
<p>KeylessWP implements the <a href="https://www.w3.org/TR/webauthn-2/" rel="nofollow ugc">W3C WebAuthn Level 2</a> specification from scratch:</p>
<ul>
<li>A custom CBOR decoder parses authenticator data</li>
<li>Custom ASN.1/DER builders construct public keys</li>
<li>PHP’s built-in <code>openssl_verify()</code> verifies ECDSA P-256 (ES256) and RSA-2048 (RS256) signatures</li>
<li>Credentials are stored in a dedicated database table with sign-count clone detection</li>
</ul>
<h4>Supported Authentication Methods</h4>
<ul>
<li>🖐 Fingerprint sensors (Touch ID, Windows Hello)</li>
<li>😊 Face recognition (Face ID, Windows Hello face camera)</li>
<li>🔑 Hardware security keys (YubiKey, Google Titan Key, Feitian)</li>
<li>🔐 Platform passkey managers (iCloud Keychain, Google Password Manager)</li>
</ul>
<h4>Features</h4>
<ul>
<li>Full FIDO2 / WebAuthn Level 2 implementation — pure PHP</li>
<li>ECDSA P-256 (ES256) and RSA-2048 (RS256) signature verification</li>
<li>Zero external libraries — only PHP’s built-in <code>openssl</code> extension required</li>
<li>Passkey registration and management from the user profile page</li>
<li>Per-credential device naming, creation date, and last-used tracking</li>
<li>Sign-count verification on every authentication (clone detection)</li>
<li>Phishing-resistant: credentials are cryptographically bound to your domain</li>
<li>Admin settings page with live usage statistics</li>
<li>Graceful fallback: the standard password form remains available</li>
<li>Translatable — all strings use <code>__()</code> with the <code>keylesswp</code> text domain</li>
</ul>
<h4>Privacy</h4>
<p>KeylessWP does not collect, transmit, or share any user data. No external services are contacted. Biometric data never leaves the user’s device — only a cryptographic public key is stored on the server.</p>
