Answer 1

The method admin() doesnt exist in the Auth classes. Use the guard admin and the method user()
if(!Hash::check($request->old_password, auth('admin')->user()->password)){
auth('admin')->user()
//will return an instance of the model of the "admin" guard. in this case App\Models\Admin::class
