let prompt = this.alertCtrl.create({
title: ‘Enter the Confirmation code’,
inputs: [{ name: ‘confirmationCode’, placeholder: ‘Confirmation Code’ }],
buttons: [

// }
//alert(‘Login Successfully’)
}).catch(function (error) {
console.log(‘error’,error)
alert(error)
// User couldn’t sign in (bad verification code?)

});
}
}

});
prompt.present();
})
.catch(function (error) {
console.error(“SMS not sent”, error);
});

}
doLogin(){
this.navCtrl.setRoot(‘HomePage’);
}

}

You can use the simple type of recaptcha verifier like this:
this.windowRef.recaptchaVerifier = new firebase.auth.RecaptchaVerifier(‘recaptcha-container’, {
‘type’: “i’m not a robot”, //add this line into your code
‘callback’: (response) => {
console.log(‘response’, response)
