Logging in Laravel 5.8 from the alternative form

I am beginner in Laravel. I make my project in Laravel 5.8

I use in my project standard Auth login system from Laravel.

I have login in my domain.com/login (original login form). I need add second login form on domain.com/index2

I make this code:

<form method="POST" action="http://domaina.test/login" id="registration_form">
 <input type="hidden" name="_token" value="RLRmSgFz3TrhXp7exjAzCDABf3OCErbf5DvxKCNI">
<div class="form-group">
 <div class="col-xs-12 col-sm-3 col-md-4 col-lg-4 padding0 paddingLogin">
  <label for="firstname" class="sr-only"></label>
  <input id="firstname" class="form-control input-group-lg reg_name loginInputFormat" type="email" name="email" title="Login" placeholder="Login" required>
 </div>
 <div class="col-xs-12 col-sm-3 col-md-4 col-lg-4 padding0 paddingLogin">
  <label for="lastname" class="sr-only"></label>
  <input id="lastname" class="form-control input-group-lg reg_name loginInputFormat" type="password" name="password" title="Password" placeholder="Hasło" required>
 </div>


 <div class="col-xs-12 col-sm-3 col-md-4 col-lg-4 padding0 form-group_pop center  ">
  <button type="submit" class="btn btn-danger zaloguj_button  ">Zaloguj</button>
 </div>
</div>
  </form>

But it's not working :( After submit this form I have redirect to main page.

How can I repair it?
