[6.x] Frontend Passkeys

[duncanmcclean]

This pull request adds passkey support to the {{ user:login_form }} and adds various other tags for setting up and managing passkeys from the frontend.

Tags

{{ user:login_form }}

To support passkeys on your login page, you will need to include the helpers script on your page:

<script src="/vendor/statamic/frontend/js/helpers.js"></script>

Then, you may combine the JS helpers & variables from the tag to add passkey support.

{{ user:login_form }}
    <!-- ... -->

    {{ if passkeys_enabled }}
        <button type="button" id="passkey-login">Login with Passkey</button>

        <script>
            document.getElementById('passkey-login').addEventListener('click', () => {
                Statamic.$passkeys.authenticate({
                    optionsUrl: '{{ passkey_options_url }}',
                    verifyUrl: '{{ passkey_verify_url }}',
                    onSuccess: (data) => window.location = data.redirect || '/',
                    onError: (error) => alert(error.message)
                });
            });

            // Enable browser autofill for passkeys
            Statamic.$passkeys.initAutofill({
                optionsUrl: '{{ passkey_options_url }}',
                verifyUrl: '{{ passkey_verify_url }}',
                onSuccess: (data) => window.location = data.redirect || '/'
            });
        </script>
    {{ /if }}
{{ /user:login_form }}

Important

For browser autofill to work, your email input must have autocomplete="username webauthn".

{{ user:passkey_form }}

The passkey form allows you to create passkeys from the frontend.

{{ user:passkey_form }}
    <input type="text" id="passkey-name" placeholder="Passkey name (e.g., My Laptop)">
    <button type="button" id="create-passkey">Create Passkey</button>

    {{ if success }}
        <p>Passkey created successfully!</p>
    {{ /if }}

    {{ if errors }}
        <ul>
            {{ errors }}
                <li>{{ value }}</li>
            {{ /errors }}
        </ul>
    {{ /if }}

    <script>
        document.getElementById('create-passkey').addEventListener('click', () => {
            const name = document.getElementById('passkey-name').value || 'My Passkey';

            Statamic.$passkeys.register({
                optionsUrl: '{{ create_url }}',
                verifyUrl: '{{ store_url }}',
                name: name,
                onSuccess: () => location.reload(),
                onError: (error) => alert(error.message)
            });
        });
    </script>
{{ /user:passkey_form }}

{{ user:passkeys }}

This tag allows you to loop through your passkeys.

{{ user:passkeys as="passkeys" }}
    {{ if passkeys }}
        <h3>Your Passkeys</h3>
        <ul>
            {{ passkeys }}
                <li>
                    <strong>{{ name }}</strong>
                    {{ if last_login }}
                        <span>Last used: {{ last_login format="M j, Y g:i A" }}</span>
                    {{ else }}
                        <span>Never used</span>
                    {{ /if }}

                    {{ user:delete_passkey_form :id="id" }}
                        <button type="submit" onclick="return confirm('Delete this passkey?')">
                            Delete
                        </button>
                    {{ /user:delete_passkey_form }}
                </li>
            {{ /passkeys }}
        </ul>
    {{ else }}
        <p>You haven't set up any passkeys yet.</p>
    {{ /if }}
{{ /user:passkeys }}

Variables:

• id - Passkey identifier
• name - User-defined passkey name
• last_login - Last time the passkey was used
• delete_url - URL to delete this passkey

{{ user:delete_passkey_form }}

This tag renders a form to delete a passkey. Most useful inside a {{ user:passkeys }} loop.

{{ user:delete_passkey_form :id="id" }}
    <button type="submit">Delete</button>
{{ /user:delete_passkey_form }}
