I can send emails for authentication in my Laravel application but when I click the verify button from the email I get redirected to a page with error 403.

I found this solution here: Missing required parameters for [Route: verification.verify] [URI: {locale}/email/verify/{id}/{hash}] because I had another problem. So in my web.php for verification I have these lines of code:

Route::get('email/verify', '\App\Http\Controllers\Auth\VerificationController@show')->name('verification.notice');
Route::get('email/verify/{id}', '\App\Http\Controllers\Auth\VerificationController@verify')->name('verification.verify');
Route::get('email/resend', '\App\Http\Controllers\Auth\VerificationController@resend')->name('verification.resend');

and the link for verification looks like this:

<a href="{{ route('verification.verify', ['id' => $user->id, 'hash' => $user->verification_token]) }}">Verify Email</a>

The verify() function in my VerificationController looks like this:

public function verify(Request $request, $id, $hash)
    {
        $user = User::findOrFail($id);

        if ($user->email_verified_at) {
            return redirect()->route('home')->with('warning', 'Your email has already been verified.');
        }

        if (!hash_equals((string) $hash, sha1($user->getEmailForVerification()))) {
            return redirect()->route('home')->with('error', 'Invalid verification link.');
        }

        $user->markEmailAsVerified();

        return redirect()->route('home')->with('success', 'Your email has been verified!');
    }

I will provide additional info if needed as soon as possible

The error message "invalid signature" usually occurs in Laravel when using the Route::get or Route::post helper to generate URLs with signed parameters, but the signature provided in the URL is not valid or has been tampered with.

In the context of your code snippet, the issue might be related to the route being protected with URL signing and the URL being accessed with an invalid or tampered signature.

Laravel provides a feature called "signed URLs," which allows you to generate URLs with a signature that verifies the integrity of the URL parameters. This is often used for sensitive operations or for protecting certain routes from being accessed without a valid signature.

To generate a signed URL, you can use the signed method of the URL helper: `use Illuminate\Support\Facades\URL;

$url = URL::signedRoute('verification.verify', ['id' => 123]);`

This will generate a URL with a signature, something like:https://example.com/email/verify/123?signature=xxxxxxxxxxxxxxxxxxxxxx

When this URL is accessed, Laravel will automatically verify the signature, and if it's valid, the request will be allowed to proceed. However, if the signature is missing, invalid, or has been tampered with, Laravel will throw an "invalid signature" error.

If you're getting an "invalid signature" error with the provided code, make sure you are generating the URL using the signed method, as shown above, and that you're accessing the URL with the correct signature. If you're accessing the URL directly from the browser, ensure that the signature is not being modified or truncated.

If you're still having trouble, you can try clearing the application cache with the following command:

php artisan cache:clear

Additionally, if you have customized the VerificationController and its logic, ensure that the verification process is correctly validating the signature before proceeding with the verification action. Double-check your implementation of the verify method in the VerificationController to see if there are any issues with the signature verification logic.
