You're encrypting the string 'password' instead of the password parameter sent with your form.

public function update($id) 
{ 
    $datas = User::find($id);
    $datas->password = bcrypt(Input::get('password'));
    $datas->admin = Input::get('admin');
    $datas->save();

    return redirect()->action('UsersController@index');
}

Thanks men i used other style of codes but your code helps me a lot.

$datas = User::findOrFail($id);

       // Validate the new password length...
       $datas->admin = Input::get('admin');
       $datas->fill([
           'password' => Hash::make($request->password)
       ])->save();

       return redirect()->action('UsersController@index');
