If you’re encountering a “Token invalid” issue when using multiple browsers in Laravel, it could be due to the CSRF (Cross-Site Request Forgery) protection mechanism. Laravel generates a unique CSRF token for each session, and using multiple browsers might cause token mismatches.
Here’s how you can solve the issue:

  1. Ensure CSRF Middleware is Enabled: Make sure that the CSRF middleware is enabled in your Laravel application. You can find this middleware in the app/Http/Middleware/VerifyCsrfToken.php file.
    protected $except = [
    // Add routes that should be excluded from CSRF protection here
    ];
  2. Be cautious when excluding routes, as this is a security feature, and excluding routes should only be done when necessary.
  3. Check Form Elements: Ensure that each form in your application includes the @csrf directive. This directive generates a hidden input field containing the CSRF token.
@csrf 1. **Session Configuration:** Verify that your session configuration is set up correctly. Laravel relies on sessions to manage CSRF tokens, so ensure that your session driver (usually configured in `config/session.php`) is properly configured. 2. **Check System Clock:** Sometimes token issues can arise if there's a significant time difference between the server and the client. Ensure that the system clocks of both your server and your machine are correctly synchronized. 3. **Browser Cache:** Clear the browser cache on all the browsers you are testing. Cached tokens may cause conflicts.

Here’s a simple example of a Blade template with a form including the CSRF token:

@csrf Name: Submit Make sure to adapt this to your actual foam structure and routes. If the issue persists, you may need to provide more specific details about your code and Laravel version for a more accurate solution.
