Laravel 8: How do i verify the users email address after registration without having to require login information?

I set up a Laravel 8 installation with Jetstream and implemented a custom user registration, where an event is fired after a successful creation of the database record event(new Registered($user));.

The initial registration process should not require a password yet, because only a selected set of users should be able to login to a dashboard in the future.

After the registration the user gets an email with a verification link, however he still needs to login in order to get verified.

I tried to remove the auth middleware in routes/web.php, however i get an error message after attempting to verify a users email address.

Route::get('/email/verify/{id}/{hash}', function (EmailVerificationRequest $request) {
  $request->fulfill();
  return view('home');
})->middleware(['auth','signed'])->name('verification.verify');

Is it possible to verify a users email address without login information?

It is possible.

You can modify files directly in Jetstream packages however I will present method adding new files and keeping original packages untouched.

Add new Controller App\Http\Controllers\VerifyEmailController.php

<?php

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Auth\Access\AuthorizationException;
use Illuminate\Auth\Events\Verified;
use Illuminate\Http\Request;
use Laravel\Fortify\Contracts\VerifyEmailResponse;

class VerifyEmailController extends Controller
{
    public function __invoke(Request $request)
    {
        $user = User::findOrFail($request->route('id'));

        if (! hash_equals(sha1($user->getEmailForVerification()), (string) $request->route('hash'))) {
            throw new AuthorizationException;
        }

        if ($user->hasVerifiedEmail()) {
            return app(VerifyEmailResponse::class);
        }

        if ($user->markEmailAsVerified()) {
            event(new Verified($user));
        }

        return app(VerifyEmailResponse::class);
    }
}

In web.php add a new route without auth middleware:

use App\Http\Controllers\VerifyEmailController;
    
Route::get('/email/verify/{id}/{hash}', [VerifyEmailController::class, '__invoke'])
    ->middleware(['signed', 'throttle:6,1'])
    ->name('verification.verify');
