laravel redirect if logged in

go to App\Http\Middleware\RedirectIfAuthenticated then change it from

public function handle($request, Closure $next)
{
    if ($this->auth->check()) {
        return redirect('/home');
    }

    return $next($request);
}

to

public function handle($request, Closure $next)
{
    if ($this->auth->check()) {
        return redirect('/admin');
    }

    return $next($request);
}

Add this to your AuthController:

protected $redirectTo = '/admin';

This tells all the redirect methods in the various traits to redirect there instead of to /home.
