# Register a user

To register a user, call **`MBAuth.registerUser()`**.

{% hint style="info" %}
The fields, name , surname , email and password are required, while the other are optional. 

The field data is an arbitrary object (array or dictionary) representing additional data that you want to pass when registering the user. It will be returned when retrieving the profile.
{% endhint %}

```dart
await MBAuth.registerUser(
      'name',
      'surname',
      'email',
      'password',
      phone: '1234567890',
      image: null,
      data: null,
    );
```
