You could catch and handle the TokenMismatchException exception in bootstrap/app.php
use Illuminate\Session\TokenMismatchException;
// ...
->withExceptions(function (Exceptions $exceptions) {
$exceptions->render(function (TokenMismatchException $e, Request $request) {
return redirect()->route('login');
});
})
However, this is blunt... every 419 is going to be redirected to login.
