### Install Passkeys for Laravel via Composer and publish migrations

Source: https://github.com/roundly-consulting/passkeys-for-laravel/blob/main/README.md

Install the package with Composer, publish the migrations, and run them. Requires PHP 8.4 (ext-json; ext-sodium for EdDSA) and Laravel 12 or 13. Set PASSKEYS_ORIGINS before use; set PASSKEYS_KEY_TYPE before migrating if using UUID/ULID keys.

```bash
composer require roundly-consulting/passkeys-for-laravel
php artisan vendor:publish --tag="passkeys-migrations"
php artisan migrate
```

### Sign in with passkey: authentication options and verify

Source: https://github.com/roundly-consulting/passkeys-for-laravel/blob/main/README.md

Generate authentication options, verify the browser's response, and log the user in. Uses AuthenticationResponseData and navigator.credentials.get() with parseRequestOptionsFromJSON().

```php
use RoundlyConsulting\Passkeys\DataTransferObjects\AuthenticationResponseData;

return response()->json(Passkeys::authenticationOptions());

$passkey = Passkeys::authenticate(AuthenticationResponseData::fromArray($request->all()));

Auth::login($passkey->authenticatable);
```

--------------------------------

### Register a passkey: return options and verify browser response

Source: https://github.com/roundly-consulting/passkeys-for-laravel/blob/main/README.md

Generate registration options for a user and verify the browser's response. The register method accepts RegistrationResponseData and a name for the passkey.

```php
use RoundlyConsulting\Passkeys\DataTransferObjects\RegistrationResponseData;
use RoundlyConsulting\Passkeys\Facades\Passkeys;

return response()->json(Passkeys::for($user)->registrationOptions());

$passkey = Passkeys::for($user)->register(
    RegistrationResponseData::fromArray($request->all()),
    name: 'MacBook Touch ID',
);
```

--------------------------------

### Browser JavaScript for passkey registration ceremony

Source: https://github.com/roundly-consulting/passkeys-for-laravel/blob/main/README.md

Fetch registration options, create a credential with navigator.credentials.create(), and POST the credential with the ceremonyId. Uses PublicKeyCredential.parseCreationOptionsFromJSON().

```javascript
const options = await (await fetch('/passkeys/options')).json();
const credential = await navigator.credentials.create({
    publicKey: PublicKeyCredential.parseCreationOptionsFromJSON(options.publicKey),
});
await fetch('/passkeys', { method: 'POST', headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ ...credential.toJSON(), ceremonyId: options.ceremonyId }) });
```

### Add HasPasskeys contract and passkeyUserHandle column to User model

Source: https://github.com/roundly-consulting/passkeys-for-laravel/blob/main/README.md

Implement the HasPasskeys contract on the user model and add the passkey user handle column in a migration. The migration uses the passkeyUserHandle() Blueprint method.

```php
use RoundlyConsulting\Passkeys\Concerns\InteractsWithPasskeys;
use RoundlyConsulting\Passkeys\Contracts\HasPasskeys;

final class User extends Authenticatable implements HasPasskeys
{
    use InteractsWithPasskeys;
}

// in a migration
Schema::table('users', fn (Blueprint $table) => $table->passkeyUserHandle());
```
