<p>Passwordless passkey login for WordPress using Face ID, fingerprint, Touch ID, and Windows Hello.</p>
<h3>🔐 Passwordless Login Is Here, and It’s Simpler Than You Think</h3>
<p><strong>Authentry</strong> brings passkey authentication to WordPress. One tap. One glance. Instantly signed in.</p>
<p>No passwords to type. No usernames to remember. No resets, no friction, no phishing.</p>
<p>Passkeys are built on the <strong>WebAuthn / FIDO2 standard</strong>, the same technology trusted by Google, Apple, and Microsoft. Authentry brings that same enterprise-grade security to any WordPress site, for free.</p>
<h3>👆 Your Users Already Know How to Use It</h3>
<p>They unlock their phone with a fingerprint or Face ID dozens of times a day. Authentry makes signing into your site feel exactly the same.</p>
<p>Here’s the flow: user taps the Authentry button <span aria-hidden="true" class="wp-exclude-emoji">→</span> confirms with Touch ID, Face ID, Android fingerprint, or Windows Hello <span aria-hidden="true" class="wp-exclude-emoji">→</span> they’re in. That’s it.</p>
<p>Enable <strong>usernameless login</strong> in settings and they don’t even need to type their email. The site finds their passkey automatically, as effortless as unlocking their phone.</p>
<p>💡 <strong>Perfect for:</strong> membership sites, WooCommerce stores, subscription platforms, and any audience that expects a fast, modern, mobile-first experience.</p>

<h3>📋 Shortcode Reference</h3>
<h3>Sign-In Button (guests)</h3>
<pre><code>[authentry_button label="Sign in with Passkey" style="default" redirect="" class=""]
</code></pre>
<h3>Add a Passkey (logged-in users only)</h3>
<pre><code>[authentry_register label="Add a passkey" style="default" class="" reload="1"]
</code></pre>
<p>Omit <code>label</code> to use the value set in Appearance settings. Set <code>reload="0"</code> to stay on the page after a successful registration.</p>
<h3>Full Passkey Management UI (logged-in users only)</h3>
<pre><code>[authentry_manage class="" title=""]
</code></pre>
<p>Lists all passkeys with rename, delete, and add controls, the same UI shown in WooCommerce My Account and the WP Admin profile page. Scripts load automatically.</p>
<h3>Shortcode Attributes – <code>[authentry_button]</code></h3>
<ul>
<li><code>label</code>: button text (default: from Appearance settings)</li>
<li><code>style</code>: <code>default</code>, <code>outline</code>, or <code>ghost</code></li>
<li><code>redirect</code>: URL to send the user after a successful login</li>
<li><code>class</code>: additional CSS class names</li>
</ul>
<h3>Shortcode Attributes – <code>[authentry_register]</code></h3>
<ul>
<li><code>label</code>: button text (default: from Appearance settings)</li>
<li><code>style</code>: <code>default</code>, <code>outline</code>, or <code>ghost</code></li>
<li><code>class</code>: extra CSS class on the wrapper</li>
<li><code>reload</code>: <code>1</code> (default) reloads the page after registration; <code>0</code>, <code>false</code>, or <code>no</code> stays on the current page</li>
</ul>
<h3>Shortcode Attributes – <code>[authentry_manage]</code></h3>
<ul>
<li><code>class</code>: extra CSS class on the wrapper</li>
<li><code>title</code>: optional section heading (default: “Security Keys”; also filterable via <code>authentry_manage_heading</code>)</li>
</ul>
<h3>🔧 Custom Login Pages</h3>
<p>Already have a custom login page? No problem. Just drop the Authentry button in and keep your existing form. No need to rebuild anything.</p>
<p><strong>✅ Recommended: Shortcode</strong></p>
<ol>
<li>Edit your custom login page</li>
<li>
<p>Add a Shortcode block:</p>
<p>[authentry_button]</p>
</li>
<li>
<p>Optionally, pass attributes:</p>
<p>[authentry_button label=”Sign in with Passkey” redirect=”https://yoursite.com/my-account/” style=”outline”]</p>
</li>
</ol>
<p>Authentry automatically enqueues its CSS and JavaScript on standard front-end pages. No extra setup needed.</p>
<p><strong>Alternative: PHP Template</strong></p>
<p>In your login template file:</p>
<pre><code>do_action( 'authentry_render_button', [ 'redirect' => home_url( '/my-account/' ) ] );
</code></pre>
<p>Any missing keys fall back to your <strong>Authentry > Appearance</strong> and <strong>General</strong> settings.</p>
<h3>Username / Email Field (non-usernameless flow)</h3>
<p>When usernameless login is off, or when a browser falls back from discovery mode, Authentry looks for a username or email field using these selectors:</p>
<ul>
<li><code>#user_login</code> (WordPress default)</li>
<li><code>input[name="username"]</code></li>
<li><code>input[name="email"]</code></li>
</ul>
<p>If the field is already filled when the user clicks the button, that value is sent automatically. If it’s empty, the user is prompted. With usernameless login on, users can often sign in without typing anything at all.</p>
<h3>Let Users Manage Their Passkeys</h3>
<p>On any member dashboard or account page (logged-in users), add the full management UI:</p>
<pre><code>[authentry_manage]
</code></pre>
<p>Or just the “Add a passkey” button with no list:</p>
<pre><code>[authentry_register]
</code></pre>
<p>In a theme template:</p>
<pre><code>do_action( 'authentry_render_manage', [ 'title' => 'Security Keys' ] );
</code></pre>
<h3>Page Builders & Late-Rendered Output</h3>
<p>If the button is printed after <code>wp_enqueue_scripts</code>, for example in some page builders or AJAX-loaded forms, fire this hook once before output:</p>
<pre><code>do_action( 'authentry_enqueue_public_assets' );
</code></pre>
<p>The <code>[authentry_register]</code> and <code>[authentry_manage]</code> shortcodes handle this automatically. Use the same hook in custom templates if styles or scripts appear to be missing.</p>
<h3>Redirects & Customization</h3>
<ul>
<li><strong>Per-button redirect:</strong> <code>redirect</code> attribute on <code>[authentry_button]</code>, or the <code>redirect</code> key in <code>authentry_render_button</code></li>
<li><strong>Global redirect:</strong> <strong>Authentry > General > Redirect URL after login</strong>, or the <code>authentry_redirect_url</code> filter</li>
<li><strong>Button HTML:</strong> <code>authentry_button_html</code> filter</li>
</ul>
<h3>For Developers</h3>
<p>See <strong>Authentry > Integration</strong> in the admin for the full reference of shortcodes, actions, filters, and REST API endpoints (<code>/wp-json/authentry/v1/...</code>). The global <code>window.Authentry</code> object is also available for advanced JavaScript integrations.</p>
<p><strong>Hook-Only Example (theme login template)</strong></p>
<p>Step 1 – In your login markup:</p>
<pre><code>do_action( 'authentry_render_button', [ 'context' => 'my-theme-login' ] );
</code></pre>
<p>Step 2 – In <code>functions.php</code> or your login class:</p>
<pre><code>add_filter( 'authentry_login_username_selectors', function( $selectors ) {
    $selectors[] = '#my-login-email';
    return $selectors;
} );

add_filter( 'authentry_redirect_url', function( $url, $user ) {

<p><strong>CS BioLogin</strong> adds passwordless sign-in to WordPress using the WebAuthn standard (FIDO2 / passkeys). Visitors can authenticate with Face ID, Touch ID, Windows Hello, or a platform fingerprint reader. Biometric templates never leave the user’s device; only public key credentials are stored in your WordPress database.</p>
<h4>What this plugin does</h4>
<ul>
<li>Adds a <strong>Sign in with Biometrics</strong> option on the WordPress login screen (with optional password fallback).</li>
<li>Lets logged-in users <strong>register, rename, update, and remove</strong> passkeys from their profile, a front-end shortcode page, or WooCommerce My Account.</li>
<li>Provides an admin screen for <strong>settings, security logs, and per-user device management</strong>.</li>
<li>Applies <strong>rate limiting and lockout</strong> on authentication attempts.</li>
</ul>
<h4>What this plugin does NOT do</h4>
<ul>
<li>It does <strong>not</strong> send user data, credentials, or biometrics to third-party servers. All verification runs on your site over HTTPS.</li>
<li>It does <strong>not</strong> store fingerprint or face images—only WebAuthn public keys and device metadata you configure.</li>
</ul>
<h4>How it works</h4>
<ol>
<li><strong>Administrator</strong> enables the plugin under <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> CS BioLogin</strong> and chooses which roles may use biometrics.</li>
<li><strong>User</strong> opens their profile (WordPress admin profile, <code>[csbisebi_device_manager]</code> page, or WooCommerce <strong>My Account <span aria-hidden="true" class="wp-exclude-emoji">→</span> CS BioLogin</strong>) and clicks <strong>Add Biometric Device</strong>. The browser shows the OS passkey/biometric prompt.</li>
<li><strong>Login</strong> — On <code>wp-login.php</code> (or WooCommerce login), the user chooses biometric sign-in. The plugin issues a WebAuthn challenge via the REST API, verifies the signed response, and creates a normal WordPress session.</li>
</ol>
<p>REST routes live under <code>csbisebi-biometric-login/v1</code> on your own site (for example <code>/wp-json/csbisebi-biometric-login/v1/auth/options</code>). No external API keys are required.</p>
<h4>WooCommerce</h4>
<p>When WooCommerce is active, CS BioLogin adds a <strong>My Account</strong> tab, checkout/account login prompts, and automatic use of the account area instead of a standalone management page.</p>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.2 or later</li>
<li>PHP 7.4+ with OpenSSL</li>
<li><strong>HTTPS</strong> on production (WebAuthn requires a secure context; <code>localhost</code> and <code>*.local</code> are allowed for development)</li>
</ul>
<h4>Privacy and data storage</h4>
<ul>
<li>Biometric samples stay on the user’s device.</li>
<li>The plugin stores passkey public keys, optional device labels, timestamps, and security log entries in your WordPress database.</li>
<li>Uninstalling the plugin (when data removal is enabled via uninstall) drops the custom credentials table and plugin options.</li>
</ul>
