Change password reset email in Laravel Breeze

I believe you will need to (i) override the sendPasswordResetNotification in your User model so that you can (ii) replace the default ResetPasswordNotification notification with your own implementation.

(i)

// app/Models/User.php
public function sendPasswordResetNotification($token)
{
    $this->notify(new \App\Notifications\ResetPasswordNotification($token));
}

(ii)

php artisan make:notification ResetPasswordNotification

You could decide to extend the original ResetPassword class here so that you can replace the buildMailMessage method with your own implementation.

If you publish the vendor assets tagged laravel-mail,

php artisan vendor:publish --tag=laravel-mail

you can edit the header Blade template in resources/views/vendor/mail/html/header.blade.php replacing the Laravel logo with your own
