The preferred way to install this extension is through composer.

or add

"tonyaxo/yii2-recaptcha": "*"

to the require section of your composer.json file.

Once the extension is installed, simply use it in your code by :

'components' => [
    'recaptcha' => [
        'class' => 'recaptcha\ReCaptchaComponent',
        'siteKey' => 'site_key',
        'secretKey' => 'key_secret',
    ],
];

You can also use this widget in an [[yii\widgets\ActiveForm|ActiveForm]] using the [[yii\widgets\ActiveField::widget()|widget()]] method, for example like this:

<?= $form->field($model, 'reCaptcha')->widget(ReCaptcha::class, [
    'id' => 'sign-up-captcha',
    'render' => ReCaptcha::RENDER_EXPLICIT,
])->label(false) ?>
