    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'username' => 'required|string|max:255|unique:users',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
        ]);
    }

    /**

     * @return \App\User
     */
    protected function create(array $data)
    {

        return User::create([
            'name' => $data['name'],
            'username' => $data['username'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }

Instead of calling Auth::routes(), register these routes manually and modify them as you need:

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register/{username}', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register/{username}', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail')->name('password.email');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm')->name('password.reset');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');

To ensure usernames are unique, add exists:users to your validator's rule for name (assuming the your users table is named users).

return Validator::make($data, [
    'name' => 'required|string|max:255|exists:users',
    'username' => 'required|string|max:255|unique:users',
    'email' => 'required|string|email|max:255|unique:users',
    'password' => 'required|string|min:6|confirmed',
]);
