using laravel guard in laravel breeze and multi authentication

Question

I'm using laravel 8 and laravel breeze for authentication and now want to use guard for authenticating different users like "admin users" and others using different tables (users, admins, so on) or even in a same table and model. how can I do that?

some information:

• I changed LoginRequest:

 if (! Auth::guard('admin')->attempt($this->only('email', 'password'), $this->boolean('remember'))) {
            RateLimiter::hit($this->throttleKey());

            throw ValidationException::withMessages([
                'email' => trans('auth.failed'),
            ]);
        }

• I created Admin model and it's table.
• I changed auth.php for adding provider and guard

when I try to login, it redirects to login page without any error.
