Unfortunately password is modified. but User cannot login in the system .it says "Invalid Password"

        $user = User::find($id);


       $modifyPassword = $request->modifyPassword;
      
     
        //Modify Password Validation
       
        if (!isset($modifyPassword)) {
            $password = $user->password;
        } else {
          
            $password = Hash::make($modifyPassword);
        }
....
 User::updateOrCreate(['id' => $id], $saveData);
