Authentry – Face ID, Fingerprint & Passkey Login

Passwordless passkey login for WordPress using Face ID, fingerprint, Touch ID, and Windows Hello.

🔐 Passwordless Login Is Here, and It’s Simpler Than You Think

Authentry brings passkey authentication to WordPress. One tap. One glance. Instantly signed in.

No passwords to type. No usernames to remember. No resets, no friction, no phishing.

Passkeys are built on the WebAuthn / FIDO2 standard, the same technology trusted by Google, Apple, and Microsoft. Authentry brings that same enterprise-grade security to any WordPress site, for free.

👆 Your Users Already Know How to Use It

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.

Here’s the flow: user taps the Authentry button → confirms with Touch ID, Face ID, Android fingerprint, or Windows Hello → they’re in. That’s it.

Enable usernameless login in settings and they don’t even need to type their email. The site finds their passkey automatically, as effortless as unlocking their phone.

💡 Perfect for: membership sites, WooCommerce stores, subscription platforms, and any audience that expects a fast, modern, mobile-first experience.

📋 Shortcode Reference

Sign-In Button (guests)

[authentry_button label="Sign in with Passkey" style="default" redirect="" class=""]

Add a Passkey (logged-in users only)

[authentry_register label="Add a passkey" style="default" class="" reload="1"]

Omit label to use the value set in Appearance settings. Set reload="0" to stay on the page after a successful registration.

Full Passkey Management UI (logged-in users only)

[authentry_manage class="" title=""]

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.

Shortcode Attributes – [authentry_button]

• label: button text (default: from Appearance settings)
• style: default, outline, or ghost
• redirect: URL to send the user after a successful login
• class: additional CSS class names

Shortcode Attributes – [authentry_register]

• label: button text (default: from Appearance settings)
• style: default, outline, or ghost

• title: optional section heading (default: “Security Keys”; also filterable via authentry_manage_heading)

🔧 Custom Login Pages

Already have a custom login page? No problem. Just drop the Authentry button in and keep your existing form. No need to rebuild anything.

✅ Recommended: Shortcode

1. Edit your custom login page

2. Add a Shortcode block:

   [authentry_button]

3. Optionally, pass attributes:

   [authentry_button label=”Sign in with Passkey” redirect=”https://yoursite.com/my-account/” style=”outline”]

Authentry automatically enqueues its CSS and JavaScript on standard front-end pages. No extra setup needed.

Alternative: PHP Template

In your login template file:

do_action( 'authentry_render_button', [ 'redirect' => home_url( '/my-account/' ) ] );

Any missing keys fall back to your Authentry > Appearance and General settings.

Username / Email Field (non-usernameless flow)

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:

• #user_login (WordPress default)
• input[name="username"]
• input[name="email"]

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.

Let Users Manage Their Passkeys

On any member dashboard or account page (logged-in users), add the full management UI:

[authentry_manage]

Or just the “Add a passkey” button with no list:

[authentry_register]

In a theme template:

do_action( 'authentry_render_manage', [ 'title' => 'Security Keys' ] );

Page Builders & Late-Rendered Output

If the button is printed after wp_enqueue_scripts, for example in some page builders or AJAX-loaded forms, fire this hook once before output:

do_action( 'authentry_enqueue_public_assets' );

The [authentry_register] and [authentry_manage] shortcodes handle this automatically. Use the same hook in custom templates if styles or scripts appear to be missing.

Redirects & Customization

• Per-button redirect: redirect attribute on [authentry_button], or the redirect key in authentry_render_button
• Global redirect: Authentry > General > Redirect URL after login, or the authentry_redirect_url filter
• Button HTML: authentry_button_html filter

For Developers

See Authentry > Integration in the admin for the full reference of shortcodes, actions, filters, and REST API endpoints (/wp-json/authentry/v1/...). The global window.Authentry object is also available for advanced JavaScript integrations.

Hook-Only Example (theme login template)

Step 1 – In your login markup:

do_action( 'authentry_render_button', [ 'context' => 'my-theme-login' ] );

Step 2 – In functions.php or your login class:

add_filter( 'authentry_login_username_selectors', function( $selectors ) {
    $selectors[] = '#my-login-email';
    return $selectors;
} );

add_filter( 'authentry_redirect_url', function( $url, $user ) {
    return home_url( '/account/' );
}, 10, 2 );
