Setup

In order to use this feature, update your \App\Models\User::class model to implement the HasEmailAddresses interface and use the HasEmailAddresses trait like the following:

<?php
namespace App\Models;
 
//...
use YottaHQ\LaravelExtendedAuth\Contracts\HasEmailAddresses;
 
class User extends Authenticatable implements HasEmailAddresses
{
    use \YottaHQ\LaravelExtendedAuth\Traits\HasEmailAddresses;
    //...
}

Now you have linked the two models and can do for example:

$user->emailAddresses()->create([
    'email' => request('email'),
]);

$emails = $user->emailAddresses;

Using the user provider for authentication

This package comes with a custom user provider https://github.com/yottahq/laravel-extended-auth/blob/main/src/Drivers/ExtendedUserProvider.php which is similar to Laravel's user provider but instead it's able to authenticate users with their secondary emails as well.

Update your config/auth.php file and change your providers.users.driver to laravelExtendedAuth like in the example project:

'providers' => [
    'users' => [
        'driver' => 'laravelExtendedAuth',
        'model' => App\Models\User::class,
    ],
 
    // ...
]
