Use Behavior

Set behavior in model

<?php
...

'behavior' => [
    'otp' => [
        'class' => lsat\otp\behavior\OtpBehavior::className(),
        // Component name
        'component' => 'otp',
        
        // column|property name for get and set secure phrase
        //'secretAttribute' => 'secret'
        // column|property name for get code and confirm secret
        //'codeAttribute' => 'code'
        
        //Window in time for check authorithation (current +/- window*interval) 
        //'window' => 0
    ],
...
]

attachBehavior with dynamic form

// create form or load secret form for each user
$dynamicModel = new yii\base\DynamicModel(['code','secret']);
$dynamicModel->addRule(['code'],'required');
$dynamicModel->addRule(['code'],'string', ['min' => 6]);
$dynamicModel->addRule(['secret'],'string');
// set secret attribute
$dynamicModel->secret = "YOURSECRET";
$dynamicModel->attachBehavior("otp", [
    'class' => OtpBehavior::class,
//            'secretAttribute' => "CustomSecretField",
//            'codeAttribute' => "CustomCodeField",
]);
// Load value code attribute
$code = Yii::$app->request->post("code");
$dynamicModel->code = $code;
// Validate otp code and secret attribute
if (!$dynamicModel->validate()) {
    var_dump($dynamicModel->errors);
}

            'QrParams' => [
                // pixels width
                'size' => 200,

                // RGB color
                'backgroundColor' => [255, 255, 255],

//                            'outfile' => '/tmp/'.uniqid(),
